Public bug reported:
This machine suspends/resumes several times a day, and uptimes measure
in weeks. This is the first or second time I've encountered this
symptom in months.
On resume, the WLAN LED didn't light up again. Looking at the kernel
log I see the stack trace below. After modprobe -r iwlagn followed by
modprobe iwlagn things are normal again.
The stack trace repeats quite a few times. The stack trace itself is
identical every time, but the iwl data changes.
Finally, the device is unassociated during all of this, as I was using
the wired interface at the time.
Trace follows:
