Could provide a full bug report please, as in:

- CPU type
- is it a SMP CPU
- are you running a SMP kernel
- board type

All the above can be provided by supplying the kernel boot messages
(preferred)

- the storage peripheral being used for this test
- is DMA being used for this periperal
- any additional block layers (eg, lvm, dm, md)
- filesystem type

Plus, please cc suspected ARM problems to the ARM _kernel_ mailing list.

Thanks.
