Those disconnects do happen for reasons that I do not understand. They

is automatic, and relatively quick.
Okay - understood.
Whilst checking various parts of my kernel, I noticed for the first
time during
testing that my current kernel configuration doesn't have SMP enabled.
This got
me thinking that perhaps there are other build options which could
have an
effect on the driver. Hence I also uploaded a copy of my .config file to
http://www.ilande.co.uk/tmp/rtl8192cu-config in the hope that maybe
this can
help you recreate the issue locally?
As I have a dual-core CPU, thus I always have SMP set. That should not
be a problem. In fact, the concurrent operation of 2 CPUs usually causes
more problems. I will review that configuration.
I'd definitely be interested to know if by duplicating that same
configuration, you see the same issues that I do.
You can now disable the logging. When the watchdog reports that contact
with the AP has been lost, that is certainly true, and the watchdog is
doing its job. In addition, nothing was received from any AP, which
leads me to conclude that the receiver has locked up for some reason. I
need to check to see what the code does to recover. Perhaps that will
help me understand the problem. In my current run that has run for 20
hours, I have had two disconnects for Reason 3, but more importantly, I
have had two watchdog restarts. It does happen on my system, just a lot
less frequently. BTW, my ping loss rate is about 3%. That is too high,
but not as bad as yours.
Interesting. Perhaps there is something different in the initial
programming of the radio that causes it to crash on my particular
hardware revision? As before, please let me know if there is anything
else you require.
ATB,
Mark.
