Description Johannes Berg 2011-03-15 17:16:50 UTC
I get all the way to do_suspend_lowlevel(), and then the system hangs.

acpi_old_suspend_ordering doesn't change anything.

FWIW, Win7 (which I still have installed for no particular reason) works fine.

It's great that the kernel bugzilla is back.

Can you please verify if the problem still exists in the latest upstream kernel?
Comment 2 Johannes Berg 2012-01-18 08:22:17 UTC
On 3.2.0-wl-66272-gb111b40-dirty (3.2 + wireless bits) the system can suspend, but not resume.
Comment 3 Johannes Berg 2012-01-20 17:13:45 UTC
Ok, actually, the system suspends using pm-suspend, but doesn't suspend using "echo mem > /sys/power/state", but doesn't wake up even with pm-suspend.

what do you mean by "doesn't suspend"?
does this command fails with an error message? or does the system just hangs?
Comment 5 Johannes Berg 2012-11-28 12:55:56 UTC
With 3.5.4, I can do "echo mem>/sys/power/state" and the system will suspend, but never resume. Before, it would get stuck (hang) somewhere during suspend, not it gets stuck & hangs somewhere in resume.

Err, no, wait ... it does resume, graphics just doesn't come back. I guess that's a separate bug.
