--- Comment #6 from Gerben Jansen ---
Heeeeey, i did the suspend/resume one more time and this time dmesg shows
similar messages but now on the sdb1 device (which does contain /MyDisk)
also after the sdb1 device re-appeared it was automatically mounted again. (due
to the default "auto" option in the /etc/fstab)
However i can imagine that nfsd would like a device to disappear and re-appear
without getting into troubles
in the dmesg now told me (booted without the "debug printk.devkmsg=on" options:

Notice that the /MyDisk file system was removed (=unmounted) and added to the
end of the list of mounted file systems (=mounted) again.
These 2 file systems (/MyLib and /MyDisk) are on 2 external USB disks. Should
those disks disappear during/after a suspend=resume and is my file system even
safe a suspend/resume ???
