/var/log/kern.log (and others) filling up!


I have been having some trouble lately with my kernel logs. The three logs that are filling up are:
/var/log/kern.log
/var/log/messages
/var/log/syslog

They are filling up with the following messages, where only the time/date changes:
Code:
Feb  1 13:00:19 DELPHI kernel: [  148.370010] WARNING: at /build/buildd/linux-2.6.24/debian/build/custom-source-rt/drivers/net/wireless/b43/dma.c:1290 b43_dma_handle_txstatus()

Feb  1 13:00:19 DELPHI kernel: [  148.370132]  =======================
These logs are filling up at a few mb/sec. I'm assuming b43 is the problem. I tried upgrading my kernel to fix this issue AFTER this problem started, but it didn't seem to do anything. I can delete the logs and reboot to get my disk space back, but this shouldn't be happening. Does anyone have any idea of how to fix this?

Thanks

If you aren't using wifi you could add the b43 driver to /etc/modprobe.d/blacklist to prevent the kernel from loading it.

Thanks for you help, but I need the wifi driver. It's really strange though, because it didn't do this until yesterday.

Any other ideas?

The only other thing I can think of is make sure the loadable firmware is the right version for the b43 module version. I run the b43 module on one of my notebooks and it isn't really the greatest. Blacklisting b43 and installing ndiswrapper may not be a bad idea. You'd probably get better overall performance out of it.

Thanks for your response.
I just got it figured out! I uninstalled some app I installed recently (sbackup) and rebooted to a non-rt kernel. I'm not sure which solved the problem, but I'm not touching anything now.

Thanks
