Today I patched the  new zen-sources-2.6.31-r1 with tuxonice. This time it was a bit more complicated since the two patches are conflicting. So I modified the tuxonice patch to apply cleanly over the zen-kernel.

Suspend to RAM works at least on my Dell Precison M65 as well as suspend to disk does.

Download the zen-sources 2.6.31-zen1 patch here: zen-sources.org. Then apply the patch to vanilla kernel sources. Afterwards download my modified tuxonice patch from here: [download#29]. Then apply it.

For Gentoo users there is a more easy way: Download my modified overlay (including the patches) from [download#30] and extract it in /usr/local/portage. Be sure to include the following line in your /etc/make.conf:

PORTDIR_OVERLAY=”/usr/local/portage”

Then emerge zen-sources-toi and buld the kernel as you wish.

To work around the black screen problem with some nvidia-drivers versions occuring with 2.6.30 kernels, discussed at gentoo forums, I had to upgrade to nvidia-drivers-190.18. Most probably this problem persists with 2.6.31. Strangely the issue did only occur on my Precision M65 with a Quadro FX350M. It did not occur with the Quadro FX3400 in my Desktop PC, Nvidia-drivers-185.18.31 are running there without any problems.

Tuxonice is not officially supported in zen-sources. So If you’re using the files above, don’t report any bugs to zen-sources.org. You are on your own.

For my Precision M65 I used the following kernel config: [download#31]

If you want to use all channels with the iwl3945 driver change the line static char *ieee80211_regdom = “US”; to static char *ieee80211_regdom = “JP”; in the file net/wireless/reg.c.

If you also own of those old 16 Bit Adaptec pcmcia scsi cards using the aha152x_cs module you might want to enable it also for 64 Bit kernels. It was masked for 64 Bit kernels somewhere before 2.6.13. I was unable to find out the reason for this so I tried to compile the module. When I insert the card, the module loads properly. Since the drive I could test it with, is currently attached to another box and in use, I can´t try it out for the moment. Once I tried I´ll keep you updated.

To enable the driver remove the line

depends on !64BIT

in the config PCMCIA_AHA152X section in /usr/src/linux/drivers/scsi/pcmcia/Kconfig and select the module in menuconfig.

Addon: I tried a SCSI cdrom with this and it works perfectly. I just filed a bug on this on bugzilla.kernel.org and hope for the driver being unmasked for future  64 Bit kernels.

If you are using this kernel on a notebook with i.e. a Core2 CPU you might be interesting to undervolt your CPU to save power and to produce less heat (keeps the fan off longer). This works like a charm on my M65. Information on this topic can be found here: aldeby.org. The linux-pch patch mentioned there is already included in zen-sources, thus you only have to perform the userspace part begnning at (3).

For image compression in tuxonice include Compressor lzo in your suspend2.conf file.

Sadly the iptables mirror target I published here does not work anymore with the 2.6.31 kernel. A newer version will be available soon on mygnu.de.

Today I patched the brand new zen-sources-2.6.30-r4 with tuxonice. This was necessary since I need tuxonice on my notebook for suspend modes and tuxonice has been removed permanently from zen-sources. Suspend to RAM works at least on my Dell Precison M65 as well as suspend to disk does.

I recommend using this version over using the r3-version, because it fixes the root exploit vulnerability mentioned on www.linux-magazine.com.

Download the zen-sources 2.6.30-zen4 patch here: zen-sources.org Then apply the patch to vanilla kernel sources. Afterwards download the tuxonice patch from http://www.tuxonice.net/downloads/all/current-tuxonice-for-2.6.30.patch-20090620-v1.bz2 and apply it.

For Gentoo users there is a more easy way:

Download my modified overlay (including the patches) from [download#26] and extract it in /usr/local/portage. Be sure to include the following line in your /etc/make.conf:

PORTDIR_OVERLAY="/usr/local/portage"

Then emerge zen-sources-toi and buld the kernel as you wish.

If you want to use all channels with the iwl3945 driver change the line

static char *ieee80211_regdom = “US”;

to

static char *ieee80211_regdom = “JP”;

in the file net/wireless/reg.c.

Today I managed to patch the brand new zen-sources-2.6.30-r3 with tuxonice. This was necessary since I need tuxonice on my notebook for suspend modes and tuxonice has been removed permanently from zen-sources. Suspend to RAM works at least on my Dell Precison M65 as well as suspend to disk does.

Download the zen-sources 2.6.30-zen3 patch here: zen-sources.org Then apply the patch to the vanilla kernel sources available from kernel.org. Afterwards download the tuxonice patch from http://www.tuxonice.net/downloads/all/current-tuxonice-for-2.6.30.patch-20090620-v1.bz2 and apply it to the kernel sources with the zen patchset already applied.

For Gentoo users there is a more easy way:

Download my modified overlay  (including the patches) from [download#24] and extract it in /usr/local/portage. Be sure to include the following line in your /etc/make.conf:

PORTDIR_OVERLAY="/usr/local/portage"

Then emerge zen-sources-toi and continue with building the kernel as you wish.

Some days ago Thorsten wrote TuxOnIce is broken in 2.6.29-zen1. Well, I wanted to have a 2.6.29 kernel, because the iwl3945 driver in 2.6.29 works the first time with a useable speed for me.  So I no longer need the hack for the ipw3945 driver I published on ipw3945 unter linux-kernel 2.6.27.

Today I managed to patch the brand new zen-sources-2.6.29-r3 with tuxonice. This was necessary since I need tuxonice on my notebook and tuxonice has been removed permanently from zen-sources. Suspend to RAM works at least on my Dell Precison M65 as well as suspend to disk does.

Since 2.6.29-zen3 has not been released as patch yet, you may download the patch I created from git here: [download#16] Then apply the patch to the vanilla kernel sources available from kernel.org. Afterwards download the tuxonice patch from http://www.tuxonice.net/downloads/all/tuxonice-3.0-for-2.6.29.patch.bz2 and apply it to the kernel sources with the zen patchset already applied.

For Gentoo users there is a more easy way:

Download my modified overlay  (including the patches) from [download#17] and extract it in /usr/local/portage. Be sure to include the following line in your /etc/make.conf:

PORTDIR_OVERLAY="/usr/local/portage"

Then emerge zen-sources-toi and buld the kernel as you wish.

The files above are not from an official zen release. Tuxonice is not officially supported in zen-sources. So If you’re using the files above, don’t report any bugs to zen-sources.org.

For my Precision M65 I used the following kernel config: [download#18]

If you want to use all channels with the iwl3945 driver change the line

static char *ieee80211_regdom = “US”;

to

static char *ieee80211_regdom = “JP”;

in the file net/wireless/reg.c.

Today I upgraded my Gentoo systems to nvidia-drivers-180.41.  I had bad news to report the last two times I upgraded nvidia-drivers in nvidia-drivers-180.37 causing strange segfaults and CTRL-C and CTRL-Z not working after nvidia-driver upgrade and high CPU usage.

Well, since I had bad news before I also want to tell you about the good news. I did not experience any problems yet with nvidia-drivers-180.41. I run Gentoo with kernel 2.6.28-zen4 #1 SMP PREEMPT on x86_64 and tried with Quadro FX3400 and Quadro FX350M. Even tuxonice works on my  Dell Precision M65 with the driver. In the past I sometimes had problems with suspending and some nvidia-driver versions.

Well, not everyone is as lucky as I am. Some cards seem not to be recognized anymore by the driver. You can read about this problem on 180.41 — no more support for 6600?

I’m quite happy to have a new working driver after the last two upgrade attempts.

Edit: Sadly I was wrong in this post. nvidia-drivers-180.41 also causes segfaults as well as 180.44 does. These segfaults occur during heavy CPU/MEM usage. (In my case running 6 instances of mencoder simultaneously on 4 cores). After downgrading again to 180.29 everything returned to normality.
