Hello all!
I have just compiled v2.6.23.1 kernel yesterday and started using
it. But it seems there are some issues with the suspend/resume... Whet
my laptop resumes it takes a lot of time, about half a minute to
resume. I watched the timings in the dmesg output and it seems it
hands either at the souncard setup or the SATA controller. (I'm not an
expert, I just guessed that based on dmesg, so I might be wrong...)
I must add that I haven't encountered this problem with any of the
previous stable kernels. The last one I have used was v2.6.22.9. And
the difference of the two configs is not essential.
I'll describe my setup:
-- IBM ThinkPad T43
-- Debian Etch

Thank you all!
Ciprian.
P.S.: For now I will stick with v2.6.23.1 to see if there are also
other problems. (I think there is also an issue with the mouse but I'm
not sure...)
