No. At first it was from a NFS-mounted volume to another NFS-mounted volume. I then found that it panic'ed the same when I copied from a local FFS volume to the same NFS volume. The NFS volumes are automounted by amd under /a. That may well have something to do with the panic: that's a recent change in my configuration; I previously used NFS mounts in /etc/fstab which didn't cause me any trouble. > Of course, it is still a serious kernel bug.

Here's the df (I removed some of the amd dummy mount points). $ df Filesystem 1K-blocks Used Avail Capacity Mounted on /dev/wd0s1a 49583 34595 11022 76% / /dev/wd1s1e 5975845 3556146 1941632 65% /home /dev/wd0s1f 148823 1290 135628 1% /tmp /dev/wd0s1g 5380597 1615221 3334929 33% /usr /dev/wd0s1e 396895 38127 327017 10% /var procfs 4 4 0 100% /proc [ ten pid...@bofh:/xyz lines removed ] pid...@bofh:/cal 0 0 0 100% /cal huuh:/home/huuh 1217519 1064153 141191 88% /a/huuh/home/huuh The failing cp is: $ cp -rp /home/beyssac/src/sendmail-8.9.3/cf/ /home/beyssac/nfs/junk/ In the above, "/home/beyssac/nfs" is a symbolic link to /cal/huuh/cal/beyssac which is automounted by amd (last line in the above df). -- Pierre Beyssac p...@enst.fr To Unsubscribe: send mail to majord...@freebsd.org with "unsubscribe freebsd-current" in the body of the message
