It turns out I'm just an idiot.
With 6.2-RELEASE, I had to boot without ACPI in order to avoid kernel
panics under load; I have a USB keyboard and apparently USB events can
cause kernel panics while the kernel is heavily loaded down (like,
say, during a 'make buildworld' or a 'make buildkernel').
So I instinctively booted the new 7.0-CURRENT kernel with ACPI
disabled as well, and it couldn't map any of my device interrupts.
When I rebooted with ACPI enabled, it actually booted and let me log
Now the only issue that I have is that sending SIGINFO to a 'dd'
process causes a kernel panic. Any ideas about that one?
