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.

For more information on the zen-sources patchset see www.zen-sources.org.

best regards

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.
