[PATCH] sleep & cpufreq problems

[PATCH] sleep & cpufreq problems

[Benjamin Herrenschmidt]

Hi !

Here are a couple of patches against current linus bk (one was already
posted to this list) that should fix a number issues related to sleep
and wakeup, especially in conjunction with cpufreq transitions.

Please test and let me know if it fixes a problem you had, it adds a new
problem, or it has no effect, stuff still doesn't work (if it used to
work and still work, no need to bug me).

Thanks !

Patches are at:

http://gate.crashing.org/~benh/ppc32-pmac-sleep-fix.diff
http://gate.crashing.org/~benh/ppc32-cpufreq-gpio-off.diff

Thanks,
Ben.

I just updated the second patch, so if you got it since my last email,
please d/l it again.

Hi Ben !

I apply your 3 patches on 2.6.12-rc1 and my ibook g4 doesn't crash anymore
after wakeup when i change the cpu speed.

My gratitude is far bigger than my english vocabulary, thank you very much!

Ok, I re-updated them, if you have sleep, cpufreq or both problems, try
and let me know.

THe first one should apply on 2.6.11, the second one applies only on top
of current bk.
