zen-sources-2.6.30-r4 with tuxonice

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 zen-sources-toi-2.6.30-r4 overlay (815) 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, discussed at gentoo forums, I had to upgrade to nvidia-drivers-190.18. Strangely the issue does only occur on my Precision M65 with a Quadro FX350M. It does 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: kconfig-precision_m65-zen-sources-toi-2.6.30-r4 (797)

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 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.

zen-sources-2.6.30-r3 with tuxonice

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 zen-sources-toi-2.6.30-r3 overlay (618) 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.

To work around the black screen problem with some nvidia-drivers versions, discussed at gentoo forums, I had to upgrade to nvidia-drivers-190.18. Strangely the issue does only occur on my Precision M65 with a Quadro FX350M.

ImportError: No module named layman.config

Today, when I tried to sync the portage overlays on my gentoo linux boxes, I got the error:

ImportError: No module named layman.config

The recent update from python-2.5 to python-2.6 has broken several applications. This issue was solved by running python-updater, which re-emerges all broken python packages. Besides from layman not working, the python upgrade may cause several other problems in portage and in the whole system. Thus just be sure to run python-updater after the python-upgrade.
