I have done some eveninfs testing, taking apart and putting together my
own initramfs. It looks like this is a kernel bug, not userspace - the
hang happens after initramfs is unpacked and after VFS and quotas are
installed, and after "msgmni has been set to 627" message but before BSG
loading message and before io scheduler initialization. And log before
init is executed from initramfs (and no modprobe is executed either, as
my wrapper does not run).

Rerepeating, same userspace generats fine initramfs for 2.6.27 and the
initramfs contents are the same except modules tree that is for
different version.

It happens on 2 of my computers, both have custom config (serial
compiled in, not modular). The hang happens before ttyS driver
initialization.

Seems like a kernel regression to me.
