Subject: via_rhine kernel crashes in 2.6.32

Hello.

Recently I've started to experience kernel crashes under heavy network
load. It may be caused by switching to .32-rc0, but as .30 crashed too, it
may be caused by switching from Vuze to Deluge (maybe it uses the network
more actively). Unfortunately, most crashes can't be detected with
netconsole, and they usually don't fit into 1280x1024 (I think the kernel
prints 2-3 or more backtraces of random processes like hostapd and scmpc
and then completely locks up). Here are two screenshots that look like
complete one-screen traces:
http://wrar.name/temp/P1010714.JPG - this is from .32-rc0
(v2.6.32-7123-g75b0803)
http://wrar.name/temp/P1010711.JPG - this is from 2.6.30 (stock ALT Linux)

Of course I have lots of "eth0: Transmit timed out" and some "WARNING: at
net/sched/sch_generic.c:255 dev_watchdog" before crash, as described at
http://bugzilla.kernel.org/show_bug.cgi?id=11663
