Hi,

The machines seem stable after disabling I/O AT DMA at the BIOS level.

My kernel is vanilla from Kernel.org. The -r510 string is because I
tried it on a -r510 also.

I tried 3.5.x, 3.6, 3.6.1, 3.6.2 with exactly the same results.

For now, I did create more volumes, rsync lors of data over the network
to the disks with no crashs (after disabling I/O AT DMA).
