[Bug 649141] [NEW] BUG: unable to handle kernel paging request - EIP: [<f959ae41>] snd_ctl_poll

[Bryce Harrington]

Public bug reported:

OOPS on maverick with stock kernel.

I was listening to internet radio, it quit playing and I could not get
the player to restart.  Looked in dmesg and saw this oops report; I had
been tailing dmesg in an xterm and roughly correlate when this oops
happened to when the music quit.

[Background]
Since upgrading to maverick last week, I've noticed this machine has system lockups up to 2-3 times a day.

I've also periodically seen short (1-sec) display blanking, usually
occurring only on one of the two monitors (and usually but not always
the monitor that has graphics changes.)
