Kernel Crash with sound driver and black screen with kdm

[agambier]

Hello,

My distribution is F13 and (sometimes) when I boot up my computer, instead of displaying the kdm screen with the login window, i've got a black screen. I have to open another terminal ATL+F2, and reboot the computer.

My computer is a DELL precision T1500.
I think it's due to a sound driver crash, for the following reasons :

1. When I'm logged in, i've got a kernel crash with the sound driver (sound/pci/hda/hda_intel.c).
2. I fixed a shutdown problem by disabling the sound notification. Here my other post. http://forums.fedoraforum.org/showth...14#post1402514
3. Here my dmesg output.

Can someone help me or tell if I should disable the all sound system ?

Thanks.
