As far as the errors from the driver goes, the first one I see is "could
not activate Heartbeat timer" (not sure yet what the heartbeat timer
does, perhaps expiring peer STAs in the IBSS network when beacons aren't
seen for some period). This is printed using some internal logging
functions and has the log level LOGP, and any message of this log level
will trigger the stack trace.

There's a few ways for enabling the heartbeat timer to fail. The first
is that some ACTIVEMODE_OFFLOAD feature is enabled, the second is that
the timer hasn't been initialized, and the third is that the actual
timer activation fails for any of a variety of reasons. There's no clues
in the log about why it failed.

However it's also not apparent whether or not failing to activate the
heartbeat timer is fatal. The driver just logs the error and continues
on. Without digging deeper into the driver I can't tell whether it's the
cause for IBSS not working; it could just be a symptom of a larger
hardware misconfiguration or even unrelated to the other observed
issues.
