Core Crashes
« on: September 16, 2008, 03:35:47 pm »
As of late I have had some issues with my Hybrid core. It was locking up quite a bit then I reinstalled and it worked fine for about a month and a half then I came home last Friday to find that X would not load and I was getting errors in the start up process that stated that my system could not write to my swap partitions. I suspect that my hard drive failed and I replaced it and reinstalled. But now I have been getting random lockups daily like I used to before I removed a problematic MD. Just wondering in general how many people have constant problems with their core or hybrid/core.

can we please not use generic terms like "lockup", "hang" and "crash"?

If somebody has a real kernel panic/oops/bug, I'd love to see a core dump.
I'm still waiting to see an unstable core without bad hardware/assembly.

best regards,
Hari

you have to use kdump.

best regards,
Hari

ps: the kexec-tools package may be your friend

Hari - I'd be happy to send mine too. It only happens occasionally, but doesn't seem to have any pattern behind when. Probably once every 2 weeks? And it does hard lock, can't do anything, and it stops routing traffic from the internal to external networks - LEDs on the keyboard flashing.... It happened only 2 days ago, so let me know which files you want and I will send them over...

EDIT - just saw your reply, looking into it right now!

hmmm.. installed, kdump doesn't have a proper man page, and each time I try to execute it, it just says it can't find the start of the coredump. I can see lots of process specific files in both /usr/pluto/coredump and /home/coredump/1 should I be pointing it to those?

you are messing kernel dumps with process dumps. Maybe some background reading would be helpful.

Perhaps I'm dumb.... Which is likely.. But could you be maybe a little more clear as to what you mean by reading? It might help if you send us in the right direction, maybe give us a few pointers? Not all of us are experts when it comes to Linux. As I have had a great deal of experience being a user of ubuntu I have very little troubleshooting experience and I am afraid I really only know enough to be dangerous.
