Most probably this commit fixes my issue. Very strange that this error didn't
appear before, it seems it exists at 2.6.30 even?

commit c55b89fba9872ebcd5ac15cdfdad29ffb89329f0

[SCSI] mptsas : PAE Kernel more than 4 GB kernel panic

This patch is solving problem for PAE kernel DMA operation.
On PAE system dma_addr and unsigned long will have different
values.
Now dma_addr is not type casted using unsigned long.
