Sure. I have updated the file (added pci_machine_1.txt and pci_machine_2.txt). The kernel configuration is already there (named ATHLON-PHOBOS), the second machine has a default SMP kernel. http://people.freebsd.org/~alepulver/disk-crash.tar.bz2 > Also, could you provide more information about what the settings are= =20 > that you are using for NFS and SMBFS (-rsize, -wsize, special=20 > mountd/rpcbind options, etc). > -Garrett I am not using nothing special here. In rc.conf: rpcbind_enable=3D"YES" nfs_server_enable=3D"YES" nfs_client_enable=3D"YES" And the commands (at different times): # mount deimos:/wxp /mnt # mount -t smbfs //administrator@mariana/c /mnt After both FreeBSD machines crashed when the problem happened (because of the NFS waiting infinitely), I started using "-i". The second command was to copy some data from a Windows machine. BTW I don't think the problem is related to NFS/SMBFS but to the disk drivers, since it happens without them too. One is ATA (has an year) and the other is SATA (new). However I am not experienced in this to tell.
