[vortex] 3c59x Driver lockup

[Ryan Moore]

I'm having a problem with several machines with dual 3com 905 cards 
(mixed configurations with a 905 and a 905b or two 905bs, etc) locking 
up, often (but not always) getting errors such as these in the kernel log:

--
Too much work in interrupt, status e003.
PCI bus error, bus status 80000020
Host error, FIFO diagnostic register 0000.
PCI bus error, bus status 800000a0
Host error, FIFO diagnostic register 8000.
(repeated over and over)
--
(note: didn't get the errors in that exact sequence, it is just a sample 
of different errors I'm getting)

Briefly looking at the archives and searching via google, it looks like 
this problem has been run into a decent amount by more than just myself.
This just started happening on a machine that has been running over a 
year without a single lockup, running a 2.4.16 kernel that was compiled 
from source (also tried 2.4.18, 2.4.19, 2.4.20, getting the problem in all).

At first I thought it was a hardware problem, but I've tried several 
different cards (all 905x) and two other motherboards and the problem is 
appearing on them as well (all three mobos are Supermicro P6DGU/P6DBU 
series.

I've also tried the `bomerang_rx(dev);` suggestion in the driver for 
2.4.20 kernel driver to see if it would make a difference, but the 
problem persisted. I'm going to do some more extensive testing when I 
get back in the office Monday, but was wondering if there were any other 
suggestions anyone might have, Thanks.
