The only non-default option I had was 'modeset=1'. From Jeff's earlier
comment I understood the probing behaviour changed.

The fundamental difference is that in 2.6.29 everything initially seems
okay, but then there is a
ata1.00: exception Emask 0x10 SAct 0x3f SErr 0x50000 action0xe frozen
ata1.00: irq_stat 0x00400008, PHY RDY changed

There's nothing frozen it 2.6.28.

Should I log a kernel bug, what's the best way forward and is there
anything more I can do to help?
