I've had a couple of other reports like this from ages ago and never got
to the bottom of it (in both cases because the reporter decided it was
far simpler to find a PCI controller instead)
Somewhere there is a subtle behavioural difference between pata_sis and
the ancient sis5513 driver. About the only way to find it would be to
boot both the old and new kernels and log every single access to the disk
controller to the point of failure (or some short way into booting) in
both cases somewhere (eg over the network) then compare them.
