https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=224479 --- Comment #25 from ota@j.email.ne.jp --- Isn't this problem because "umount" happens before "swapoff"? I also use NFS swapfiles from time to time and when I forget to swapoff such files before shutdown, kernel panics, too. # mount -t nfs xxx:/yyy /mnt/nfs # dd if=/dev/zero of=/mnt/nfs/swap bs=1M seek=999 # swapon /mnt/ntfs/swap # --- use swap.... # i.e. mount -t tmpfs tmp /mnt/tmpfs; dd if=/dev/zero of=/mnt/tmpfs/fill # shutdown -p now I'm not sure what kinds of side effects will happen if we "swapoff" before "umount", though... -- You are receiving this mail because: You are the assignee for the bug.help
