I would like to confirm this bug too!
The system is totally irresponsive during freeze neither remote login is
available and the kernel gentle restarter (Alt+SysRq+REISUB‎ ) does not
work too.
Some strange lines in the log files (I attached them):
/var/log/kern.log
Dec 10 13:40:12 hardnut kernel: [ 8.030845] pci_bus 0000:06: Raising

Dec 10 13:43:21 hardnut kernel: Kernel logging (proc) stopped.
some strange lines from dmesg
