AF9015 suspend problem

AF9015 suspend problem

[Jose Alberto Reguero]

When I have a af9015 DVB-T stick plugged I can not recover from pc suspend. I 
must unplug the stick to suspend work. Even if I remove the modules I cannot 
recover from suspend.
Any idea why this happen?

Did you asked this 7 months ago from me?
I did some tests (http://linuxtv.org/hg/~anttip/suspend/) and looks like 
it is firmware loader problem (fw loader misses something or like 
that...). No one answered when I asked that from ML, but few weeks ago I 
saw some discussion. Look ML archives.

I think that is another problem. If I blacklist the af9015 driver and have the 
stick plugged in, the suspend don't finish, and the system can't resume. If I 
unplugg the stick the suspend feature work well.

Bug 15294 -  Oops due to an apparent race between udev and a timeout in 
firmware_class.c

I haven't examined those yet, but I think they could be coming from same 
issue.

I found my problem. Was a quirk that I have in the kernel parameters:
usbhid.quirks=0x07ca:0xa815:0x04
Without the quirk, the system go to sleep an can wake, although only the first 
time. The second time the system don't sleep. Perhaps I have some wrong in my 
scripts.
