[LARTC] IMQ causing network card reciever lockups

[LARTC] IMQ causing network card reciever lockups

[Andre Tomt]

Hi!

For the past months, my home nat-router has been acting up, locking
random ports on the quad port ethernet NIC after 3-6 hours of use. After
lots of lots of eliminating and debugging of modules, I have circled in
on the IMQ-modules.

So, IMQ locks up my ethernet ports. I'm running a quad D-Link DFE-580TX
using the mainline sundance driver, kernel version is 2.4.23-rc3 based.
The same happens with the becker driver, but is seems to revive the port
after a ifdown/ifup cycle (might have been a fluke). In the kernel log I
get this information (with the mainline driver), and I have to reboot to
revive the port from coma again.

I can't see anything obvious in slabinfo, but the
"netif_queue_stopped=1" in the log above looks curious.

Any fixes I can try? QoS is pretty much useless here without IMQ ;-)
