Fwd: Thinkpad hotkeys and USB audio not working after resume in 3.0.x

Fwd: Thinkpad hotkeys and USB audio not working after resume in 3.0.x

[Pedro Ribeiro]

Hi,

I'm hitting a bug with my thinkpad T400. After resuming from
Hibernate, the thinkpad hotkeys and my USB audio card do not work at
all.
Suspending to RAM and resuming seem to solve the problem, but after
another hibernation it comes back again.

This only happens with TuxOnIce but not with the vanilla kernel.

Rafael, can you please point out from the top of your head if there
was any change that could have caused this?

Thanks in advance.

Kind Regards,

Sorry for my slowness in getting back to you Pedro.

When you invoke swsusp, is it in exactly the same way that TuxOnIce is
invoked? I'm wondering whether modules are unloaded and services stopped
in one scenario that are handled differently in the other.

Hi Nigel,

Thanks for your response.

I just tried using echo disk > /sys/power/state using both methods
(swsusp and ToI) and the result is the same.

With swsusp the keys and the USB interface work fine, but with ToI
they stop working until I suspend to RAM.

Regards,
Pedro

Forgot to say, I tried reverting "PM / Runtime: Rework runtime PM
handling during driver
 removal" but it didn't help.

Okay; thanks for ruling that out. I'll seek to take a look today.
