(Those are all the 2.6.12 UMLs I've tried.)
Basically, userspace never starts: the last two lines I see are
VFS: Mounted root (ext2 filesystem) readonly.
line_ioctl: tty0: ioctl KDSIGACCEPT called
[halt]
(If I reboot into 2.6.11.9-bs5 with the same root fs, the next line
I see is init's banner.)
A trace of the main thread shows it sleeping, perhaps because, well,
userspace hasn't started yet:

Any ideas?
(And sorry for not getting around to getting a backtrace for so long
after the release of 2.6.12.*.)
