Looks like the DMA errors are back in 6.1-RC with ATA or at least similar
DMA errors. The new one froze my machine with an error like "Error while
performing DMA_WRITE command". A new twist to the WRITE_DMA Timeouts of 5.4.
I am starting to think that they aren't going to get the ATA issues all
worked out anytime soon so they are changing the errors. ;-)

And of course no automatic reboot on panic.
