Jeff any libata changes that might explain this?

I've been bugtracking this the last couple of days, but getting nowhere.
Same configuration was working less than a month ago. It uses pata_platform.c which in turn registers an ata device.

This segment looks just as it usually does.

Any suggestions on how to bugtrack this, setting init=/bin/sh doesn't do anything.

Best wishes
