I escaped to the loader prompt and type 'set debug..' and then booted.
The devinfo output is attached.

Doing the kldload with debug.bootverbose I now get this:

isab0: found ICH7 or equivalent chipset: Intel ICH7M watchdog timer
ichwd0: detached
ichwd0 failed to probe at port 0x1030-0x1037,0x1060-0x107f on isa0
isab0: found ICH7 or equivalent chipset: Intel ICH7M watchdog timer
ichwd0: <Intel ICH7M watchdog timer> at port 0x1030-0x1037,0x1060-0x107f
on isa0
isab0: found ICH7 or equivalent chipset: Intel ICH7M watchdog timer
ichwd0: Intel ICH7M watchdog timer (ICH7 or equivalent)
ichwd0: timer disabled
ichwd0: timer enabled
ichwd0: timeout set to 28 ticks
ichwd0: timer reloaded
(repeats infinitely)


Thanks,

Doug
