>Description:
When booting the FreeBSD 8.1-RELEASE DVD on an HP Proliant DL785 G6, the process is eventually interrupted before sysinstall with the following error message:

Fatal trap 12: page fault while in kernel mode
cpuid = 0; apic id = 00
fault virtual address = 0x18
fault code            = supervisor read data, page not present
instruction pointer   = 0x20:0xffffffff80595e68
stack pointer         = 0x28:0xffffffff80cc24e0
frame pointer         = 0x28:0xffffffff80cc2520
code segment          = base 0x0, limit 0xfffff, type 0x1b
                      = DPL 0, pres 1, long 1, def32 0, gran 1
processor eflags = resume, IOPL = 0
current process = 0 (swapper)
trap number = 12
panic: page fault
cpuid = 0
kernel trap 12 with interrupts disabled

If I boot with ACPI disabled, it hangs at the "Trying to mount root from ufs:/dev/md0" stage.

FreeBSD 7.3-RELEASE successfully makes it to sysinstall, as does 9-CURRENT (I haven't tried finishing the installation process with either).

 Can try to boot custom-built FreeBSD 8.1 kernel with debug support and obtain
 debugging information?
 At the very least, please provide messages from verbose boot leading up to the
 crash.

 Sorry for the late response. The underlying issue must have been fixed
 at some point, as FreeBSD 8.2-BETA1 is unaffected by this bug.
