So you mean v2.6.21-rc1 vanilla works > fine? Do you know a commit ID that works for sure? I'd like to bisect Nope, 2.6.21-rc1 vanilla does not work. 2.6.20 works. 2.6.20-gitX worked until some acpi change broke it, the below patch fixed that for me. That got merged in a later 2.6.20-gitY, but then some other patch broke it again so that 2.6.21-rc1 is broken. Not much luck there :-) So it looks like: - c5a7156959e89b32260ad6072bbf5077bcdfbeee broke 2.6.20-git - f3ccb06f3b8e0cf42b579db21f3ca7f17fcc3f38 should fix that. - Something later than f3ccb06f3b8e0cf42b579db21f3ca7f17fcc3f38 broke it again. > this, but this way i might just find that ACPI change that got already > fixed later on (and then got re-broken). Yeah, it gets trickier. I'll try f3ccb06f3b8e0cf42b579db21f3ca7f17fcc3f38 now and see if that works, then bisect to 2.6.21-rc1 to find the other offender. I hope the other offender didn't get added before f3ccb06f3b8e0cf42b579db21f3ca7f17fcc3f38, we'll see :-) -- Jens Axboe
