Yes, it does; I tried that one during bisecting, and then re-tried before 
writing my first mail, just to ensure I hadn't messed something up.

IIRC I also tried to modify my 2.6.30-rc6 checkout to reinstate the calls 
to spin_unlock() and local_irq_enable_in_hardirq() that were replaced with 
spin_unlock_irq() by patch 295f000.  This also didn't cause the problem to 
go away. Anyway, I have no clue what all this code does, so that was just a 
shot in the dark! :-)

Cheers,

  Richard
