Hello.

Thank you for your reply.

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.

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.

Thanks and Best Regards,
Ale
