Bug#700513: linux-base: Cannot resume after suspending (laptop model HP CQ61 410SH)

Not sure if I'm doing this right, but I'm reporting the results here.

Could you also try 3.7-trunk-686-pae, from the experimental suite?

Done, I just installed it without doing anything else (it mentioned that it may be missing some drivers).

I still have the same error. Should I try anything else? The dmesg, or something like that?

That error message means that the kernel supports APM but the BIOS
doesn't!

Try going through section 1(a) 'Test modes of hibernation' in:
http://www.kernel.org/doc/Documentation/power/basic-pm-debugging.txt
but instead of writing 'disk' to /sys/power/state, write 'mem'.

That should help to work out where this is going wrong.

OK, so I tried:

echo freezer > /sys/power/pm_test

echo mem > /sys/power/state

echo devices > /sys/power/pm_test

echo mem > /sys/power/state

echo platform > /sys/power/pm_test

echo mem > /sys/power/state

echo processors > /sys/power/pm_test

echo mem > /sys/power/state

echo core > /sys/power/pm_test

echo mem > /sys/power/state

For all of them, I get this:

ata1: softreset failed (device not ready)

ata2: softreset failed (device not ready)

But it always comes back to live. Am I doing it right?

I can't find if there is a log file that contains the results of these tests.

Thanks

Ben.
