Funny you should ask. :) I saw that, and took a look. I'm getting the following error, from a verbose dmesg: isab0: found ICH10 or equivalent chipset: Intel ICH10DO watchdog timer ichwd0: <Intel ICH10DO watchdog timer> on isa0 isab0: found ICH10 or equivalent chipset: Intel ICH10DO watchdog timer pcib0: allocated type 4 (0x830-0x837) for rid 0 of ichwd0 pcib0: allocated type 4 (0x860-0x87f) for rid 1 of ichwd0 ichwd0: ICH WDT present but disabled in BIOS or hardware device_attach: ichwd0 attach returned 6 That's different than the error message I got before, but watchdogd still fails. I didn't have a chance to check the BIOS settings until today, and there is no entry for anything even closely resembling this. The only things I actually have disabled are the parallel port, and the "Dell Trusted Platform Module," neither of which I can imagine would be relevant. I'm happy to provide more info.
