Which logs do you want,... then ones with the patch applied? Or without
and just from current 3.1?

(Anyways,... the error messages are just the same as before,... MAC is
in deep sleep, etc....)

Well...

I had a hardware problem with that notebook,.. it didn't boot anymore at
all.... got it to the vendor, and they replaced the whole mainboard
which had some hardware failure (including - I guess - the WiFi chip).
It reports to be the very same WiFi chipset.

The original problem was now resolved, but when I've used WLAN the first
time (and ever since than), I got the error messages as described in the
thread of [1] and [2].
Back then, I used the same kernel/same config/same build of it ... as I
had before the old mainboard broke,... and which worked perfectly fine.

I've used the double quotes,... as it didn't stop working completely. It
works.... but every now and then the system freezes for some ~30 seconds
during which it massively prints the "MAC is in deep sleep messages".

Thanks,
Chris.
