Description Jeld The Dark Elf 2002-01-09 17:25:27 UTC
Multiple problems trying to unmount loop device mounts

1. If lock-break support is compiled in, the system freezes instantly if umount
is issued
2. If lock-break is disabled ( either the kernel is not patched or the option is
not activated in config ) umount /dev/loop? gives "device busy" error. umount
/mountpoint seems to work, but actual loop device stays locked and has to be
manualy unlocked using losetup.

The only place I found so far where this is causing real trouble is when trying
to convert system to LVM. The lvmcreate_initrd script fails. Also there might be
some nasty surprises when writing CDs.

Sorry, forgot the versions

kernel: 2.4.16 ( preempt, lock-break, XFS and ACPI applied )
glibc, gcc etc. from the current portage tree without any modifications

Try merging baselayout-1.7.0 (on rsync in 1/2 hr -- we're using a real /etc/mtab
instead of a symlink) and using kernel 2.4.18_pre3 which includes loopback
device fixes.  This should change things dramatically for the better.  I'm
marking this as fixed; resubmit a bug if you still have problems.
