[Info-vax] axpbox crashed when logged out.

[Timothy Stark]

Folks,

 

I discovered a bug in axpbox when I attempted to log out.  Axpbox crashed
with messages:

 

Exception in SYM thread: Not implemented: pci0.1(sym53c810).disk0.4(file):
Unknown SCSI command 0x1b.

: /home/sword7/axpbox/src/src/Disk.cpp, line 1495.

Emulator Failure: Threading error: SYM thread has died:
/home/sword7/axpbox/src/src/Sym53C810.cpp, line 1501

Stop threads: cpu0 srl0 sym ali kbd

Freeing memory in use by system...

pci0.1(sym53c810).disk0.0(file): Closing file.

 

I checked SCSI reference for command 0x1B and it performs loading/unloading
or starting/stopping unit.  I believe that logout routines attempted to
unload CD om DKA400 (53C810). 

I was able reproduce errors at some chance when I attempted to log off.

 

Does anyone have any experience with that?
