I was trying to run a bunch of raw IO's (/dev/raw/rawN) at once to several (well 25) disks, trying to maximize IO's/second by repeatedly reading the same block of a disk, and got the following oops. I hit this both on a netfinity and NUMAQ box. The oops does not always occur, but it is fairly easy to hit on the NUMAQ (8 cpus). The program I'm using reads one block, seeks to the start, and repeats. I have not tried earlier kernels.
