Description of problem:
Acer Aspire 6935G.
No sound after suspend mode on kernels 3.6.X. On previous kernels (3.5.X) sound works fine.
Version-Release number of selected component (if applicable):
kernel - 3.6.1-1.fc17.x86_64
kernel - 3.6.2-4.fc17.x86_64
Steps to Reproduce:
prerequisites: Acer Aspire 6935G , Fedora 17 with kernel 3.6.X
1. boot to fedora 17, kernel 3.6.X - sound works
3. resume - no sound, but sound card present
I have a possibly related issue:
I have been running FC16 for some time w/o incident. Latest working kernel was 3.4.11-1.fc16.i686.PAE. Yesterday I performed a 'yum update' and got kernel 3.6.2-1.
Sound stopped working. System rolling in (from /var/log/messages):
Oct 26 15:20:47 blackhole udevd: timeout: killing '/sbin/modprobe -bv pci:v00008086d000027D8sv00001028sd000001DEbc04sc03i00' 
Oct 26 15:20:48 blackhole udevd: timeout: killing '/sbin/modprobe -bv pci:v00008086d000027B8sv00000000sd00000000bc06sc01i00' 
In addition to broken sound functionality, the system does not shutdown (disks stop spinning, but shutdown screen hangs). I have to manually complete the shutdown (hold power button). System will reboot, but sound still broken and /var/log/messages rolls in above error msgs. Got to be 500MB big before I noticed this!!!
When I reboot and come up with 3.4.11-1, all is well!
I am running FC16 on a Dell Precision 390
with kernel - 3.6.3-1.fc17.x86_64 worked again.
