Long Stall When Rebooting or Halting
When I updated from Fedora 21 to 22, more often than not I saw my system stalling when unmounting remote NFS shares during a reboot or halt. I could manually unmount with no problems.
I do not know what causes the stall.
The stall occurred only with Fedora 22 but not 21.
I did stumble across a possible pattern.
Typically the stall occurred when I booted to run level 3 and logged in as root to perform maintenance. Logging in as non-root and the problem did not occur.
The stall was related to my NFS share /home/public.
I added the following sledge hammer to root’s .bash_logout:
ls /home/public >/dev/null
That seemed to avoid the unmounting stall. I do not know why this happens only with root and only in non graphical boot.
More WTF fodder?
