No, this was not posted so far. I will try to debug the loop issue
soonish. The outlined idea above only prevents the issue without

I looked at it a bit more and realized that we can replace spinlock
by mutex. This should fix remaining problems here, and hopefully do
not introduce any others. Could you test two attached patches, and
if they do not crash intermediately :-) retest again with
CONFIG_LOCKDEP ?
After about 1 hour of testing, I see no problems and no lockdep warnings.
BTW, patch #2 did not apply to wireless-testing as your previous patch changing
the locking in ps.c has already been applied. Fortunately, it was not much of a
problem to get it applied using wiggle.
