[systemd-devel] 220 udev boot regression: timeout, giving up waiting for workers to finish

Hello Tom, all,
with 220 I get a severe boot time regression:
Startup finished in 30.751s (kernel) + 11.706s (userspace) = 42.458s
which used to be
Startup finished in 703ms (kernel) + 890ms (userspace) = 1.593s
(this is a VM)
It seems udevd --daemon spends 30 seconds timing out in the initramfs:
[ 0.384519] systemd-udevd: starting version 220
[ 30.736381] systemd-udevd: timeout, giving up waiting for workers to finish
and then some more in the real root:
$ systemd-analyze blame
(full journal at http://paste.ubuntu.com/11372265/, but it's not very
I bisected this to
udevd: move file descriptors to Manager
this is hard to revert individually as there are lots of other recent changes
in udev around this commit, but any version before that commit is fast
and doesn't give that timeout error.
Current trunk as of commit 185abfc3 still has that problem, so it
wasn't fixed by one of the recent udev commits.
Does anyone else see this too? Any idea what causes this?
