Actually, my bad, my txrx kernel is built with this patch:



==== //depot/tuxrx/linux/kernel/linux-mips-2.6/drivers/mgmt-bus/rcon.c#2 - /home/andy/tmp-p4/tuxrx/linux/kernel/linux-mips-2.6/drivers/mgmt-bus/rcon.c ====
874c874
< #ifdef CONFIG_TUXSTOR
---
> #ifdef CONFIG_ONSTOR_TUXSTOR


However, kernels built without that patch were run for hours w/o crashing
as long as I didn't try to send any packets across the mgmtbus.  I haven't
even tried that since I built the current kernel I'm running.

I'm also not loading an FP image.
