I am effectively a Windows user. pun:/var/crash$ uname -a FreeBSD pun.isi.edu 6.0-CURRENT FreeBSD 6.0-CURRENT #12: Wed Apr 27 18:28:51 PDT 2005 root@pun.isi.edu:/usr/src/sys/i386/compile/PUN i386 The kernel was compiled immediately after cvsup. I've built a debug kernel and on the last lockup was able to get into the debugger and try to force a panic, but it never dumped me a core to /var/crash - locked up and rebooted. I did get a file in /var/crash called bounds that's only 2 bytes long, an ASCII "2" and a newline. I suspect that the file system is deadlocking somewhere, but I don't know how to go about ruling that in or out. I can get to the debugger, so any clues what to look for on the next lockup, given that a crash dump is unlikely? I'm happy to provide any info I can. -- Ted Faber http://www.isi.edu/~faber PGP: http://www.isi.edu/~faber/pubkeys.asc Unexpected attachment on this mail?
