Yeah - either bootloader or BIOS - whatever talked to the NIC most recently.

Are you sure?

I thought I removed all calls to tulip_stop_rxtx() in the initialization
code path and didn't think it would get called. Did I overlook one?
Can you add "dump_stack()" to tulip_stop_rxtx() failure case?

Can you also modify the driver version to make sure you are using
the correct/most recenly built module?

And the please post the dmesg output from the driver again (plus 10
lines of output  before and after).

thanks,
grant
