Subject: new regression in 2.6.25-rc3: can't resume from suspend to ram, ata1 errors
Date: Mon, 25 Feb 2008 22:57:24 +0200	[thread overview]
Message-ID: <8f53421d0802251257o75d2975dldcfb99a2dc5e3539@mail.gmail.com> (raw)

On my T61p, 2.6.25-rc2 seems to wake up fine from suspend to ram.
Not so 2.6.25-rc3: it hangs on suspend to ram, with a blank screen.

At one point I got lucky and got this on console (wrote down by hand,
there could be typos):
ata1: COMRESET failed (errno=-16)
ata1: COMRESET failed (errno=-16)
end_request: I/O error, dev sda sector 200554
Buffer I/O error on device dm-0, logical block 256

git bisect points at this commit:
commit 559bbe6cbd0d8c68d40076a5f7dc98e3bf5864b2.
power_state: get rid of write-only variable in SATA

After reverting 559bbe6cbd0d8c68d40076a5f7dc98e3bf5864b2
on top of 2.6.25-rc3 the kernel again resumes from suspend to ram.
