>Description:
On trying to do an initial load of FreeBSD 5.2.1, the floppy boot process fails with a kernel panic like this:

usb...
..
ata0: at 0x1f0 irq 14 on atapci0
ata0: [MPSAFE]
ata1: at 0x170 irq 15 on atapci0
ata1: [MPSAFE]
pci0: <serial bus, SMBus> at device 31.3 (no driver attached)
pci0: <multimedia, audio> at device 31.5 (no driver attached)

Fatal trap 9: general protection fault while in kernel mode
cpuid = 0; apic id = 00
instruction pointer     = 0x58:0x2d6c
stack pointer           = 0x10:0xf80
frame pointer           = 0x10:0x0
code segment            = base 0xc00f0000, limit 0xffff, type 0x1b
                        = DPL 0, pres 1, def32 0, gran 0
processor eflags        = interrupt enabled, resume, IOPL = 0
current process         = 0 (swapper)
trap number             = 9
panic: general protection fault
cpuid = 0;
Uptime: 1s

Can't activate Scroll Lock at this point, so can't retreive prior probe messages before this.

Can confirm that hint.acpi.0.disable=1 (appears to be the default setting).

>How-To-Repeat:
Install kern.flp, power up, sit back.  Swap to mfsroot.flp when prompted.  Watch for kernel panic when OS is first loaded.

Same floppies worked fine on several other (older) machines I have here.
