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.It does, I changed some configuration options from =m to =y and
it started working again. Unfortunately I'm unable to find the
exact option that fixed it since I don't have the previous
configuration anymore and random attempts to trigger the problem
again failed.
Maybe you just miss /dev/console in initramfs? That would trigger the
kernel forked modprobe with that major/minor.
Some device nodes must be created or included in initramfs before any
action is taken.
