Maybe you could provide more details? Like kldstat output & perhaps the output from either mount or df? Is either NFS or MFS loaded as a module? Are you certain your modules match your kernel? If they or anything else is loaded as a module, can you try compiling everything (but osf/1) into your kernel statically? I think I've at least partially replicated your environment, and I cannot duplicate this crash: <2:11pm>vivaldi/gallatin:~>df -h . /tmp Filesystem Size Used Avail Capacity Mounted on locus:/cs/locus/home1 9.9G 4.9G 4.9G 50% /a/locus/cs/locus/home1 mfs:22 124M 4.3M 110M 4% /tmp <2:11pm>vivaldi/gallatin:~>uname -srm FreeBSD 4.0-RELEASE alpha <2:11pm>vivaldi/gallatin:~>sysctl hw.model hw.model: COMPAQ AlphaServer DS10 466 MHz <2:11pm>vivaldi/gallatin:~>cp /tmp/sshd_config . <2:11pm>vivaldi/gallatin:~>kldstat Id Refs Address Size Name 1 2 0xfffffc0000300000 314ae8 kernel 2 1 0xfffffe000204c000 22000 osf1.ko Cheers, Drew ------------------------------------------------------------------------------ Andrew Gallatin, Sr Systems Programmer http://www.cs.duke.edu/~gallatin Duke University Email: gallatin@cs.duke.edu Department of Computer Science Phone: (919) 660-6590 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message
