Possibly an issue with preempt on top of my tree. Builds fine UP & SMP

Can you send the gcc error messages of these ?
(A patch would be nice too)

Could be related to the usb-driverfs changes, 2.5.3-dj1 is still cooking

The ext3 related oops, hmm. Oopsing in generic_file_write seems odd.
I'm wondering if the system was in such a state at this point that the
subsequent oopses are just noise.

an answer for this.
