OK.  I ran through the patches that were included in 3.4.0-1 and what
wound up in 3.4.1.  The only additional patch in 3.4.1 is:

commit 577bd3ef6eed18ea3c866b2f25b14aa5e139b41f

    USB: cdc-wdm: cannot use dev_printk when device is gone
    
    commit 6b0b79d38806481c1c8fffa7c5842f3c83679a42 upstream.
    
    We cannot dereference a removed USB interface for
    dev_printk. Use pr_debug instead where necessary.


which seems unrelated to login issues.

3.4.0-1 had 3 additional intel wireless related fixes, but again
unrelated to login issues.

I suspect something in the initramfs changed if it's persistent.  You
might try rebuilding the initramfs (save the current one first) for
3.4.0-1 with whatever you have for current userspace on your box and see
if it also fails.
