This is a kernel problem, so you should report it to one of the kernel-related
mailing lists (linux-pm, for example, CC-ed).

Now, we've had a couple of similar reports recently and one of them seems
to indicate a problem with libata (http://lkml.org/lkml/2007/6/3/106).

Have you built the kernel yourself or do you use a distro one?

I use the distro kernel: 2.6.20-16-generic.

Then I think you should report the problem to the distributor in the first
place.
