 Hoi,

 The SysRq-t output was already in my original bug report.  For your 
convenience, I've extracted just the SysRq-T part in the attached log.  The 
output was intermingled with some page allocation failures, but these I've 
removed again.  I've left in a few page allocation failures, hung tasks and a 
SysRq-l for good measure.

 I'm now trying to reproduce it with fewer processes and loaded modules.

 Regards,
 Arnout
