Thanks! There have been several changes improving support for that
chip since 2.6.32.y, so it will probably take a few tries to pin this
one down.
Do you know how other kernels between 2.6.32 and 2.6.37 did?
Please test the attached patch, for example by using the following
instructions:
0. prerequisites
apt-get install git build-essential
1. get the kernel history, if you don't already have it
git clone \
git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
2. fetch latest 2.6.32.y+drm.z
cd linux
git remote add squeeze-drm \
git://kernel.ubuntu.com/smb/linux-2.6.32.y-drm33.z.git
git fetch squeeze-drm
3. configure, build, test
git checkout squeeze-drm/master
cp /boot/config-$(uname -r) .config; # current configuration
scripts/config --disable DEBUG_INFO
make localmodconfig; # optional: minimize configuration
fakeroot -u make deb-pkg; # optionally with -j<num> for parallel build
dpkg -i ../<name of package>; # as root
reboot
... test test test ...
Hoppefully it reproduces the bug. So
4. try the patch
cd linux
git am -3sc /path/to/the/patch
fakeroot -u make deb-pkg; # maybe with -j4
dpkg -i ../<name of package>; # as root
reboot
... test test test ...
I'd also be interested to hear whether the microphone jack works.
Thanks for your help and patience,
Jonathan
