Bug#317062: umount -a hangs in strcmp with 2.6.11/12



Package: busybox-udeb
Version: 1:1.00-3
Severity: important
Tags: d-i

On 2.6.11 or 2.6.12 on i386, in d-i, but ONLY if the d-i image is built
to use initramfs, and not it if uses a regular initrd, when /proc,
/dev/pts and /dev are mounted, umount -a hangs. strace shows it has
called umount syscall on each of these; /dev and /dev/pts are busy and
fail. ltrace shows it spinning in a strcmp loop. gdb shows it hanging in
mtab_getinfo, looks like the linked list has a loop in it.
