2.6.29 works OK

2.6.30-rc1 with your patch ... seems to hang when it should be
mounting the root directory.
Is it worthwhile doing a git bisect?
It probably is, since it should work with my patch, so something else
changed, maybe in the SCSI stack.
What would be the best approach?
- if the kernel boots, it's obviously 'good'
- but what if the kernel hits the 'BUG', should I apply your patch then?
If it doesn't work with your patch, would it be 'bad' then?
One thing I know is that the MESH HW has "issues" that make it very
sensitive to alignment DMA buffers, it's possible that the SCSI stack no
longer aligns some stuff ?
Hmm, great... how can I verify this?
