Ok, the WARN() in your patch from Sunday (quoted below) appeared in my logs.
I've just noticed now (but it is the 3rd or 4th time already in dmesg, that
is why it appears "Tainted")
I don't if the situation leading to the WARN() in your patch is the same
one which used to kill my wireless connection before (with the oops
in iwl_eeprom_query16 that started this thread), but the fact is
that my wifi is still working.
Here is the log:
[ I have the full dmesg from sunday up to now, with
lots of s2ram cycles in the middle. I can send it if needed ]
