Default Bug#628444: me too

I've been seeing similar problems with my "Intel Corporation Centrino
Ultimate-N 6300".

Like others, the problems seemed to start around 2.6.39.

Like othes, the card flakes out a day or two after booting, and a reboot
always fixes the problem. Occasionally it stays working for longer.

Like others, I've added RAM. But as far as I can recall the upgrade
happened well before any poblems started appearing.

Any ASPM settings are at their default.

I'll try wd_disable=1 as a workaround for now.

Meenakshi, will the patch you mentioned be applied in 3.3?

Below is a syslog excerpt from around the time of failue. It seems to
support Meenakshi's suggestion that it's related to the queue getting
stuck.

I get some kind of OOPS but I'm guessing this is just because the driver can't
communicate with the card when the module is being unloaded:
