[1.] mount/umount blocked [2.] mount/umount block forever when invoked, both on a partition of my IDE hard drives and on my IDE CDROM. The mount and the umount processes (from the output of ps) are in a state of uninterruptible sleep and strace shows that they are blocked waiting for the mount or umount library call to return. [3.] mount umount blocked [4.] Linux version 2.4.6 (root@f-ammollo.reitek.com) (gcc version 2.96 20000731 (Linux-Mandrake 8.0 2.96-0.48mdk)) #4 Mon Jul 16 14:22:22 CEST 2001 [5.] N/A [6.] mount /dev/cdrom or umount /mnt/win_c2 (see fstab below) [7.1.] If some fields are empty or look unusual you may have an old version.
