Subject: [BUG] OOPS 2.6.24.2 raid5 write with ioatdma
Hi all,
I got a raid5 oops when trying to write on a raid 5 array, with ioatdma loaded
and without DCA activated in bios:

It seems like aync_tx cannot process the xor (trying to access ioatdma but
failed ?).
When I enable DCA in system bios I cannot boot, the ioatdma subsystem failed to
initialize, it stalled at:
ioatdma: ioat_dma_test_callback(00008086)
