Forgive me if this been has been aired before. At random intervals
our 780 console says:
trap type 9, code = 0, pc = xxxxxxxx
panic: Protection fault
This message is repeated 3 or 4 times, after which we get
?INT-STK INVLD
HALTED AT .......
whereupon the machine picks itself up, dusts itself off and starts
all over again. 'xxxxxxxx' is in _dzrint, in the code:
if(tp->t_line == NETLDISC) {
c &= 0177;
BKINPUT(c, tp); <--- a macro in bk.h
} else
......
We have a 780 running 4.2 with 56 lines of DZ and 16 lines of Emulex
CS21 (=DMF32). We do run the bk discipline on a few of the DZ lines,
but not on any of the DMF's (although I can't be sure about the last
part). I'll be very grateful for any ideas on this one, please mail
me if you can help. (If you want any solutions I get, mail me and
I'll forward them.)
Regards,
geoff
