SubjectNe2000 clone on 2.2.5ac6
I have recently upgraded an old 486 to a less old Compaq prolinea
w/16mb. One
of the cards is an unmarked NE2000 clone (using a UL0020 chip, which I
managed
to find a setup program for).

This card worked fine on the 486 with a similar setup, but on the Compaq
it
sporadically generates errors:

Apr 21 14:34:40 betty kernel: eth1: timeout waiting for Tx RDC.
Apr 21 14:34:52 betty kernel: eth1: timeout waiting for Tx RDC.

Apr 21 15:42:33 betty kernel: eth1: timeout waiting for Tx RDC.
Apr 21 16:07:27 betty kernel: eth1: timeout waiting for Tx RDC.
Apr 21 16:07:31 betty kernel: eth1: timeout waiting for Tx RDC.
Apr 21 16:07:35 betty kernel: eth1: timeout waiting for Tx RDC.

The timeout errors are usually accompanied by NFS and/or FTP freezing.
This
happens on almost any large NFS/FTP transfer on the local network.

I tried changing the IRQ and that seemed to reduce the errors (the
'unexpected TX-done'
is from before I did this). I also increased the timeout in ne.c to
100ms, but it
still times out.

I suspect some kind of problem with that network card on a Compaq, and I
wonder if
anyone else has had similar problems and how have they solved them? (OK
the obvious
solution is to junk the NE2000 and get a better card but...)
