mount(1) at boot hangs in spa_namespace_lock

Gang,
for a few weeks now I can't get a CURRENT system to boot. I am using the
zfsloader and have root fs on ZFS. This has worked flawlessly for more
than a year.
The last message printed is "Mounting local file systems:" (from
rc.d/mountcritlocal) and the system hangs until I push reset. Ctrl-C etc
are ignored. However, CTRL-T says that mount is running in
spa_namespace_lock, and the "r"untime increases at 1 second per second
which looks like it is busy spinning on that lock.
What can I do to diagnose and solve it? I do have a customized
kernel config, which lookslike this. Anything wrong with it?
