So I am indeed bisecting this, but it is slow - cause last time just after 5
reboots and hours of testing the kernel froze after I marked it as good and
started compiling the next one and since I did not find a git bisect undo to do
git bisect bad after it, I used git bisect reset and git bisect start from that
commit as bad to v2.6.33 as good - and how I am stuck:

martin@shambhala:~/Computer/Shambhala/Kernel/2.6.33-2.6.34-bisect/linux-2.6>
git bisect log

I ran into a non booting kernel with d3ae8562d43fe2b97d605dd67dc67bf8fa9b956a,
it oopsed with a backtrace in ext4 and readahead I don't want to think about
deeply, so I skipped it. Then it put me just a few revisions after 2.6.33, a
kernel that didn't make much sense for me to test - I did nonetheless, it was
good as expected. Then it took me just a few revision after the non working
kernel. Consequently this one didn't boot as well and I skipped it. After that
git bisect took me prior to 2.6.33, git log from
5be796f0b842c5852d7397a82f8ebd6be8451872 gives me

    296 commit 6b7b284958d47b77d06745b36bc7f36dab769d9b
    297 Author: Linus Torvalds <torvalds@linux-foundation.org>
    298 Date:   Thu Dec 24 13:09:41 2009 -0800
    299 
    300     Linux 2.6.33-rc2

on line 300. But I told git that v2.6.33 was good. It can't be serious about
asking me to test a kernel *prior* to 2.6.33!

Testing is really slow as as it seems even after the fifth reboot and some
hours of uptime it can still freeze. So I need about half a day to be quite
sure that a kernel is good. I won't waste my time going prior to 2.6.33 which
is known good to make this experience even more painful that it was already.

So I ask for advice on how to proceed.

Well at least its clear now, that the freeze was introduced way prior to
2.6.34-rc1. I would have liked it the other way around.

According to git its still

martin@shambhala:~/Computer/Shambhala/Kernel/2.6.33-2.6.34-bisect/linux-2.6>
git bisect skip
Bisecting: 2518 revisions left to test after this (roughly 11 steps)
