Subject: 2.6.31.14: firewire_net issue in generic_sync_sb_inodes

Hi,
  I have a laptop temporarily connected via firewire 1394a to another machine.
The machine cannot sync using Alt+SysRQ+s since some conditions. Sometimes it
locks up completely and only keyboard leds are flashing and CPU fan runs at
max speed. Attached is one stacktrace I have, the other lockups are more serious
and until I find a serial cable I cannot tell you more. I cannot go for 2.6.32 or
higher here but in theory could test them temporarily. There are two firewire ports
on this Asus L3C/S laptop.
