dmesg of 2.6.30-rc2 with ff69.. reverted
Hardware: IBM Thinkpad X40, 1.2Ghz Pentium M 1.5GB ram
Software: Debian unstable 32bit
ff69f2bba67bd45514923aaedbf40fe351787c59 caused a regression when booting-up on
my setup. See
http://bugzilla.kernel.org/show_bug.cgi?id=13087
for reference. This issue has been fixed with
f461ddea0af8b98e2b7940eba9c693b0ee44d64a. Unfortunately ff69.. also caused a
resume hang on my setup, which is _not_ yet fixed.
Problem: 2.6.30-rc2 hangs after in the second suspend/resume cycle when
resuming. The fan and harddisk spin up and the lcd light switches on (and shows
the blinking cursor) but then the machine hangs. Only holding down the power
button for 4 secs helps. The suspend indicator light does not switch to the
blinking mode like it does when resuming normally (before it switches off
completely). Reverting ff69.. on top of 2.6.30-rc2 fixes the issue.
Latest kernel I tried is v2.6.30-rc5-96-ga4d7749. But then reverting f461.. and
ff69.. didn't fully fixed the problem: I could only resume two times (instead
of only once) before the machine hung when resuming.
Kernels before ff69 work flawless (at least the ones I've tested, and I'm
updating -linus from git fairly often).
I'll add the dmesg one suspend-resume cylce of 2.6.30-rc2 with ff69 reverted.
