Title:
Occasional crashes referencing btcoexist
Status in linux package in Ubuntu:
Incomplete
Bug description:
About once every month the system halts and has to be power cycled.
When looking at the previous boot log, it shows some references to
btcoexist right before crashing, consistently every time. ubuntu-bug
is not picking up the previous boot log showing the problem so here is
the last bit of log written from when the problem happens:
