For the other mystery hangs, the last message in syslog is this:
type=1503 audit(1349642278.078:46): operation="open" pid=5234
parent=5145 profile="/usr/lib/firefox/firefox{,*[^s][^h]}"
requested_mask="::rw" denied_mask="::rw" fsuid=1002 ouid=0
name="/dev/nvidiactl"
No clue why "audit" is reporting a denied(?) request by firefox to write
to nvidia, and then hanging ... Hmmm don't know what to make of this.
