Hi guys,
so besides the point that the Ubuntu 8.10 kernel has a broken driver
for the Intel 4965 cards which will crash my X61 after less than one
minute uptime when it connects to my access point, I have my dmesg
full with warnings from the latest wireless-testing kernel.
I know that we have discussed this before and Johannes' patch at least
turns it into warnings instead of killing my system completely, but I
am still surprised why this hasn't been fixed.
Attached is one of the dmesg snippets. They occur multiple times per
minute.
Regards
Marcel
