My system hasn't been able to dump core on any of its recent panics, which makes debugging rather hard (though I'm currently suspecting a faulty CPU -- it's crashing more since I replaced the last one, which died). Although all the panics have been in the same place -- various parts of the FFS code. Is some part of my setup wrong? ben@scientia:~$ grep dumpdev /etc/rc.conf dumpdev="/dev/wd2s4b" ben@scientia:~$ swapinfo Device 1K-blocks Used Avail Capacity Type /dev/wd2s4b 160650 0 160522 0% Interleaved ben@scientia:~$ It always tries to dump core, but fails with some error which I don't recall (I normally just write down the panic message and any other info like "fs = /usr".) -- Ben Smithurst | PGP: 0x99392F7D ben@scientia.demon.co.uk | key available from keyservers and | ben+pgp@scientia.demon.co.uk To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
