This is very surprising -- we just bought a bunch of Linksys 5 port
switch kits, and each box came with a pair of PNIC-II cards with very recent
dates.  I didn't think they would be changing chips.

You turned debugging on, and didn't enabled write-behind in the
/etc/syslog.conf.

What process died?  Try running ksymoops.
This doesn't sound like a typical Ethernet driver problem.

I just tried my Comet PCI card and it seems to work fine.  I'm in the
process of putting a bunch of packet through the system.  I have about a
million packets through it so far, and I'll run it overnight.

I have updated the v92 tulip driver to correctly handle the built-in MII
transceiver of the Centaur (Comet on CardBus), but the change is minor so
I'll wait for a few more changes before doing a new test release.
