I did some testing on un-patched kernels:
It seems this was broken after 2.6.35:
# good: [26845f585fad66dc23d87dad89d403cd64b48780] [SCSI] remove fake "address-of" expression
and before 2.6.36-rc2.
2.6.36-rc1 won't boot for me, and neither would the kernels
generated by my attempt to git-bisect this further.
Thanks,
Ben
