SubjectPROBLEM: lvm gets stuck during booting due to recent uevent change
From
After commit ebf4127cd677 "kobj_uevent: Ignore if some listeners
cannot handle message" in the current development tree lvm gets stuck
during booting and never recovers.

The machine has Ubuntu 11.10. Here is what happens:

An init script (/scripts/init-bottom/udev in initrd) issues command
"udevadm control --timeout=61 --exit".

At the same time udevd is executing "/sbin/lvm vgchange -a y" (from
/lib/udev/rules.d/85-lvm2.rules) that calls ioctl to resume a logical
volume. After that lvm gets stuck forever. Booting continues after the
61 second timeout.

Here is part of lvm backtrace from gdb (ioctl is called just before
dm_udev_wait from another function):

#0 0x00007f56d6d37797 in semop () from /lib/x86_64-linux-gnu/libc.so.6
