Until a few days ago, I was running OpenBSD 2.8-beta on a generic
i386 box with a Kingston 10/100 Ethernet card, supported by the dc
driver. Shortly after getting my 2.8 CD in the mail, I upgraded my
machine to OpenBSD 2.8 from the CD. After finishing the upgrade, my
ethernet card no longer works, and I get "dc0: watchdog timeout"
every few seconds on the console.
I looked at the manpage for the dc driver, and it suggests that this
message might be caused either by a loose cable or interrupts not
reaching the card. I verified that the cable was securely seated.
I didn't have any IRQ conflicts before the upgrade, and as nearly as
I can tell by looking at the BIOS output and the kernel messages, I
still don't have an IRQ conflict.
I searched the mailing list archives, and the only mention I could
find of the problem suggested reading the man pages for dc.
I have since upgraded to OpenBSD 2.8-stable and the problem persists.
I can provide my dmesg output if that would be useful it tracking down
