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
