kern/124127: [msk] watchdog timeout (missed Tx interrupts) -- recovering

[Mark Atkinson]

Wow, not sure what to blame for that charset nightmare.  Apologies.
Here's the original message:

On the unpatched -current kernel, built

FreeBSD hellfire.filament.org 9.0-CURRENT FreeBSD 9.0-CURRENT #14: Mon

I recieved the following panic today related to this:

Fatal trap 12: page fault while in kernel mode
cpuid = 0; apic id = 00
