Please see http://bugzilla.kernel.org/show_bug.cgi?id=8456
That seems to resemble the symptoms you describe.


No, I don't think. The delay I observe is on resume (suspend is very
fast). Moreover, I have no SATA. It seems that my problem came from
pcmcia.

Now for the suspend to disk. With default setting (/sys/power/disk ==
platform) my laptop (vaio PGC-FX701) fails to poweroff; it stays with
backlight on, a white screen, and if I power it off manually afterward
it did not resume.

By doing echo shutdown > /sys/power/disk the laptop *do* power off (it's
very slow, but I think that's related with the 60 secs delay commented
in the other post). Then it resume --- text console did resume ok ---
but the virtual console with X do not come back. I had to do a
ctrl-alt-backspace thing.

Any hints? More data?

Could you please test the 2.6.22-rc2 kernel? Also, if it still doesn't work
properly, could you apply the hibernation/suspend patchset available from
http://www.sisk.pl/kernel/hibernation_and_suspend/2.6.22-rc2/patches
on top of it and see if that helps?


Uf, I will try to find the time. I am on my way to try to compile
2.6.21.2 now. Problem is that a kernel compile "the ubuntu way" last
hours here. If there is an expert on make-kpkg here, I could use some
advise. I'd prefer to test patches over a 2.6.21 stable release, to
avoid mixing symptoms from an experimental -rc...
