System panics during reboot
A system ``panic'' may occur when there is a fatal error that the
system cannot correct - most often caused by an
improperly configured device or device driver. In a panic
situation, the system prints a panic message. If the Kernel
Debugger (kdb) package is installed, control transfers
to the kernel debugger program.
If you have just installed new hardware,
there may be an address or interrupt conflict with other
hardware on the system. Power down the computer and verify that
all controllers are properly seated and jumpered. Use
vendor-supplied software to diagnose hardware conflicts and
change address or interrupt values as needed.
If the problem is not hardware-based, you can restore the
previous kernel (which includes the previous device configuration):
Press the reset button (or power the computer off, then on
again if you have no reset button).

If the problem is not hardware-based but you think you can
correct it by accessing your filesystems, do the following:
If you previously created emergency recovery boot media, follow
the instructions in
``Recovering an unusable system''.
Otherwise go to Step 2.
If you did not create emergency recovery boot media, use the
Install Diskette to repair your system. See
``System with multiple operating systems does not boot UnixWare''.
