Subject: tulip Ethernet driver messes up USB keyboard
Hi lists,
After installing an old 100Mbit PCI Ethernet card to my machine, it has
complained a few times about spurious interrupts ("nobody cared") at a
random time of the day. After the oops is reported, my USB keyboard (HP
smart card keyboard) stops working properly -- it has lots of delay, it
misses some keystrokes and also causes "stuck keys". Strangely enough my USB
mouse continues to work without problems. Apparently the USB controller and
the Ethernet card share an interrupt line. Un-/replugging the keyboard does
not help.
So far I have simply rebooted to fix the issue. I haven't been able to
reproduce this on will despite my best attempts.
The Ethernet card is driven by the tulip driver and is listed as "ADMtek
NC100 Network Everywhere Fast Ethernet 10/100 (rev 11)" in lspci. My
motherboard uses the Intel H77 chipset (ASRock H77 Pro4/MVP)
Here are two slightly different examples of the oops report; the effect is
the same:

These are after a fresh reboot...
