Subject: iwl3945: page allocation failure. order:5, mode:0x8020
Date: Wed, 14 Oct 2009 16:14:32 +0300 [thread overview]
Message-ID: <878wfenmmf.fsf@purkki.valot.fi> (raw)
Hello,
your friendly iwl3945 bug reporter here :)
I updated to latest wireless-testing (tag master-2009-10-13) and I got
a page allocation failure with my Thinkpad X60s. I admit that memory
is tight on my laptop, but it has 2 GB of RAM and everything should
still work IMHO.
I didn't reboot during update, I only did 'modprobe -r iwl3945;
modprobe iwl3945', so there's a small chance that something went wrong
during update. But I still suspect something else is wrong because I
have never seen this error before.
After a fresh reboot I wasn't able to reproduce the problem. But, if
needed, I can do more testing later on.
Here's the log:
