ULE panic

Hi

After about 2 minutes on my SMP system, I get the following panic.
Sadly this is the best report I can give because the system wedges
so solidly it won't even crashdump or drop into the debugger.

Fatal trap 12: page fault while in kernel mode
cpuid = 0; lapic.id = 00000000
fault virtual address   = 0x38
fault code              = supervisor read, page not present

processor eflags        = interrupt enabled, resume, IOPL = 0
