Hi, I just had a werid crash. It crashed with the message panic: jump to 0 Could anyone tell what this means? I found where it executes the code (in l.s) but can't seem to understand how it would get there. Mind you this is 2.9 on 11/44. Also should I worry about it? Thanks inadvance Brad Smith bradley!brad

I had exactly the same problem on our 11/45 when fooling around with 2.9. I found that one of the interrupt vectors had not been initialized and, when the device interrupted, it ended up calling an interrupt service routine at location 0. My first suggestion is to check your l.s to make sure that all of your devices are configured. My problem was with RP03s -- they're so old that it's no wonder that Berkeley didn't have them configured properly. You might also try putting a halt at instruction location 0 and looking at the stack after it halts. It should show you where you were before it bombed. Good luck, -- Bob Hoffman, N3CVL Pitt Computer Science

I think that this is due to a hardware problem. Something like a device signaling an interrupt, but not supplying a vector. But I am not a PDP-11 expert. -- --------------------- Alan Fargusson. { ihnp4, sftig, amdahl, ucscc, ucbvax!unisoft }!drivax!alan
