Loopback device hangs on mount command

Loopback device hangs on mount command

[Bill Rossi]

[1.] Loopback device hangs on mount command.

[2.] Mounting a loopback device hangs the process.  Eg.  Issuing

     losetup /dev/loop0 fsimg
     mount /dev/loop0 /mnt

     will hang at the mount command.  The mount process cannot be
     killed, nor can the loopback device be destroyed with losetup.

Widely known and reported problem with 2.4 kernels before 2.4.3.  Please
search archives before posting such problems.

Either apply Jens loop patches (available on via your ftp.kernel.org
mirror), apply a recent -ac patch (which includes Jens patches), or upgrade
to 2.4.3 (which also includes Jens patches).

Later,
Tom
