Comment 1 for bug 50313

Hi,
same thing here. I've got a Thinkpad T60 with Intel Centrino Duo:
uname -a = 2.6.15-25-686 #1 SMP PREEMPT Wed Jun 14 11:34:19 UTC 2006 i686 GNU/Linux

My / is on /dev/sda3 and ext3, my /home is on /dev/sda6 and xfs. Swap is on /dev/sda5.

The "hanging" does not happen if booted with i386 Kernel.
