Hi!

I am seeking help with encircling the cause of:

[Bug 16376] random - possibly Radeon DRM KMS related - freezes
https://bugzilla.kernel.org/show_bug.cgi?id=3D16376

I started a bisection as described in which has been painful for me - at=20
least for a first time bisection -, but after the second skip of a non-
booting kernel git points me to a kernel that is outside of the initial=20
range between good and back.

good is: [60b341b778cc2929df16c0a504c91621b3c6a4ad] Linux 2.6.33

bad is: bad: [64ba9926759792cf7b95f823402e2781edd1b5d4] Merge branch 'for-
linus' of git://git.open-osd.org/linux-open-osd

After skipping the last non booting kernel, git bisect put me to=20
5be796f0b842c5852d7397a82f8ebd6be8451872 which is just 300 lines after=20
2.6.33-rc2.

Obviously I am not interested in kernels prior 2.6.33. Should I just do a=20
"git bisect good" without trying the kernel or is there some other remedy?=
=20
its 11 cycles already without testing anything outside the initial=20
good/bad range and it takes about half a day to be somewhat sure that a=20
kernel is good, so I'd like to avoid testing versions outside this range.

My bug comment #35 contains a log of the bisection[1].
