Chris,
To force a panic on an x86 system using GRUB, you'll first need to boot kmdb. This can be accomplished by adding the 'kmdb' option
to the multiboot line in menu.lst. Rather than hacking your menu.lst:
- power your machine on
- arrow to the OS you want to boot in GRUB
- type 'e'
- arrow to the line that says 'kernel /platform/i86pc/multiboot'
- type 'e' again
- type a space, then the string kmdb. It should read: kernel
/platform/i86pc/multiboot kmdb
- Hit return
- Type 'b' (for boot)
After the system boots, you should be able to drop to kmdb via the console key sequence F1-a (simultaneously, like L1-a on SPARC
machines).
Once you drop to kmdb, type:
$<systemdump
This should dump core and reboot.
This is all contingent on what caused the system to hang. You may or may not be
able to get to kmdb.
hth,
John

I have experienced two hangs so far with snv_51. I was running snv_46
until recently, and it was rock solid, as were earlier builds.
Is there a way for me to force a panic? It is an x86 machine, with
only a serial console.
