With heavy network traffic my computer completely freezes.
To reproduce, I visit a big website or download a big file from a quick site, e.g. a kernel from ftp.kernel.org
The problem occurs on 2.6.20-ubuntu-latest, stock 2.6.21.3 and 2.6.22-rc5 (no difference seen)
using madwifi/trunk w/default options on an SMCWPCI-G EU on x86-64 smp (intel core 2 duo).
I've attached my .config for 2.6.22-rc5. Alt-sysrq doesn't work after the crash, and I get no messages from ath_pci in the kernel logs, even though I set 'sysctl -w dev.ath.debug=0xFFF'
This is what happened right before the crash (from /var/log/kernel.log):
