(That bit is understandable. I must've configured it too big!)

They are diagnostic messages, and many times totally expected and normal.

Ahhh.

The TT: driver is definitely expected. (I would be very worried if you did not get that one.)
Same with the DRVPAR shrinking. It's a warning that is not important here, as you do not use DRVPAR for dynamic tasks anyway.

Ah.


The EXCOMn partitions are an 11M thing, but as far as I can remember they are also totally expected.

That is a very weird and unexpected stack pointer. RSX normally have the stack in rather low addresses.

Wonder if it's related to the tape controller that isn't actually technically present.


Not sure exactly what you configured, but maybe something wrong in all your answers... :-)

I'll grab the log when back at my desk.


After reboot:

boo [1.54]rsx11m
MCR -- Task not in system
ins $boo
boo [1,54]rsx11,\,\m
[no output]

I seem to be TERRIBLE and SYSGEN.

Well, since the initial boot failed, any subsequent boots of that image I would expect to fail equally bad.

It could have been unclean memory at some random address. This system also tends to randomly crash on first-time boots, too sometimes. A couple halts and it usually works then.
