[comp.sys.next] panic attack

adonis1@nwnexus.WA.COM (Adonis Corporation ) (09/09/90)

When trying to boot from my CDC Wren6 660M hard drive I receive
the following :

trap: cpu 0 th 0x10005500 proc 0x4095ae0 pid 0 pcb 0x10dca000
traceback: fp 0x4000ff2
called from pc 040018e4 fp 10dcbf95 4-args 0407e8d8 04023ed8 00002004 20390406
last fp 0x10dcbf95
panic: (cpu 0) 1111 emulator trap
panic: (cpu 0) thread_block

In the ROM monitor, 'recorded system error codes' reads:

old error code: 0
last error code: 73

If I try to continue the reboot I get a repeating message:

sc: didn't complete


The panic attack doesn't seem to happen when I boot from an optical 
disk rather than my hard drive.

Anyone know what this means and/or how I can find out for myself?
Thanks.
