Hello Nico,

This issue is caused by memory allocation failure when allocating rx memory in isr. (From Yi's point) If you are interested in tracking it, please report a bug at http://www.intellinuxwireless.org/bugzilla/ for further tracking.

Best Regards,
Ximin

Subject: [ipw3945-devel] iwlagn: Cannot allocate memory on 2.6.29-rc4-ikn-00001-gd5b5623

Hello!

After several rmmod & modprobe iwlagn, several suspends I get the following
netlink answer:

[8:42] ikn:~# ip l s wlan0 up
RTNETLINK answers: Cannot allocate memory

[dmesg attached]

The interesting part: The rest of the system is still working fine.

I cannot upgrade to a newer version due to Bug #12705, as reported on
13 Feb 2009.

Sincerly,

Nico
