hi list,

some helpful soul on the alsa-userlist advised me to put a textfile with

*options snd-hda-intel index=0 disable_msi=1*

in /etc/modprobe.d, in order to get *snd-hda-intel* properly working: since yesterday- evening the driver works like a charm.

is some kind soul out there who can tell me the exact meaning of the phrase *--disable_msi=1*?


googling did not help me out.
*this remark about googling is not true anymore*

i found this:

I used snd-hda-intel.disable_msi=1 and this actually helped! Now the nforce nic works w/o problems. So it was the audio driver causing havoc on the nic. ...

Unless someone finds and fixes what causes such problems, I'd therefore suggest the patch below to let MSI support to be turned off by default.
