Hello,
I just updated to FreeBSD 6.2-PRERELEASE/amd64 as of 2 hours ago. I'm seein=
g=20
the same behaviour with both the panic and the weird device name.=20
By sheer luck I figured out how to get into DDB though :), so I can now=20
provide a backtrace.
Fatal trap 18: integer divide fault while in kernel mode
instruction pointer =3D 0x8:0xffffffff801c02d5
stack pointer =3D 0x10:0xffffffff80864a80
frame pointer =3D 0x10:0xffffffff80864ad0
code segment =3D base 0x0, limit 0xfffff, type 0x1b
=3D DPL 0, pres 1, long 1, def32 0, gran 1
processor eflags =3D interrupt enabled, resume, IOPL =3D 0
current process =3D 0 (swapper)
trap number =3D 18
panic: integer divide fault
Uptime: 1s
Cannot dump. No dump device defined.
Automatic reboot in 15 seconds - press a key on the console to abort
--> Press a key on the console to reboot,
--> or switch off the system now.

disabled in the BIOS, and the Controller is from nVidia, not Promise, afaik.
Please let me know what other info I can provide.=20
The previous mail is quoted below for reference.
