Tulip based card locking after a strobe.

[Bradley Marshall]

Hi all,

I've got a tulip based 10/100M ethernet card - made by a
company called LinkPro.  The card gets detected fine on boot
with the 0.91g drivers from the website, but not with the
version distributed with 2.2 kernel source.

The problem appears when I strobe the machine - after the
first strobe, the network on the machine just hangs.
I can see the link lights flashing with received packets,
but it appears to go no further than that.  If I remove the
modules and reinsert them, the problem appears to go away
until the machine gets strobed again.

The output from tulip-diag seems to indicate that there is no
Rx buffers left, which would presumeably be why I can't see
the network from this machine.

Any ideas on what could cause this?

Attached below is the full output from tulip-diag while in
the crashed state, /proc/pci and the kernel bootup messages.
