 to 2.6.24.2

Hello!

I'm using XFS. dmesg -s32000 does not help - no more output. In messages 
there is also no relevant output. Other than what I've posted here:
http://lkml.org/lkml/2008/2/21/76

Sorry but i cannot recompile the kernel on all machines again - another 
downtime is not possible at the moment.

Stefan
