Description Thierry Vignaud 2012-09-06 09:13:49 CEST

From times to times (every twice month maybe) kernel sometimes oops on umounting a fat USB hard disk with:
VFS: Busy inodes after unmount of sdd6. Self-destruct in 5 seconds.  Have a nice day...
BUG: unable to handle kernel NULL pointer dereference at 00000000000000f8

See attached trace (3.5.3-desktop-2.mga3).

Note that the USB hard disk remains plugged. I only run "umount /run/media/foo/bar"

Sorry, but this bug saw no action since over 2 yrs ago. 
No cauldron package has stayed the same since then.

Closing as OLD

Please reopen if this report is still valid for _current_ cauldron and/or fully
updated Mageia 4
