 Chipset: Integrated Single Chip ULi(ALi) M1689
 Tried with both ataahci and ahci. Both have the same result.
 Panic Message:
 Fatal trap 12: page fault while in kernel mode
 cpuid = 0; apic id = 00
 fault virtual address = 0x0
 fault code = supervisor read instruction, page not present
 instruction pointer = 0x20:0x0
 stack pointer = 0x20:0xffffffff80e1e6b0
 frame pointer = 0x20:0xffffffff80e1e700
 code segment = base 0x0, limit 0xfffff, type 0x1b
 = DPL0, pres 1, long 1, def32 0, gran 1
 processor eflags = interrupt enabled, resume, IOPL = 0
 current process = 0 (swapper)
 trap number = 12
 panic : page fault
 cpuid = 0
 Uptime: 1s
 Cannot dump. Device not defined or unavailable.
 Debugger is bilt in kernel, but is unable to dump with savecore, no 
 dumps found.
 This is on server so I'd like to keep it as 8.0-RELEASE.
