[gdm-list] GDM won't start after MOBO and Graphics Card change

[Hans Kraus <hans hanswkraus com>]

Hi,

after a Hardware failure I had to change the motherboard and graphics
card on my Linux machine. OS is Debian Wheezy 64bit.

GDM won't start any more, the starting process seems to hang. I get the
warning:
----------------------------------------------------------------------
root robbe:~# [ 241,248138] INFO: task jbd2/dm-l:1889 blocked for more
than 120 seconds.
----------------------------------------------------------------------
in a shell window.

What shall I check and/or set up?

Regards, Hans
