Kernel panicking in 6.2 and 7-CURRENT -- interrupt issues

[youshi10 at u.washington.edu]

Hello,
      I'm trying to install 7-CURRENT on my desktop, locally instead of on a virtual machine, and I'm running into an issue where the kernel almost always panics on boot with my motherboard (ASUS P5N-SLI E), due to some sort of interrupt assignment / probing issues.

Observations:
      1. 7-CURRENT (built) never properly detects the interrupts on the system.
      2. 7-CURRENT (May ISO snapshot) doesn't properly detect my USB keyboard, but boots and runs sysinstall.
      3. 6.2 RELEASE panics if I don't boot FreeBSD up into "safe mode", due to an issue with the ohci driver (I think the error message had something to deal with device adding / enumeration and not being able to find a memory / interrupt address).

      First off, if I could get some of the command line arguments to pass to the kernel to emulate safe-mode, that would be much appreciated. Second off, if anybody has any ideas on how to debug this issue, I'll go off and try to determine what the cause is. If it's anything like it was before (clean out /usr/obj, rebuild), I'll be ok. Otherwise, I'll have to purchase more parts and build another dedicated FreeBSD system :(..

Thanks,
-Garrett
