Yes, it seems that for some reason the ATA driver isn't able to access the drive on these later kernels.
Therefore I would guess it can't talk to your drive properly. Recent kernels couldn't bring up a network device on one machine here, staring at it further /proc/interrupts showed 0 interrupts associated with that device. Adding pci=biosirq to the kernel commandline got that working again, so give it a try. Press 'A' at the grub prompt and addit on the end of the bad kernel's commandline.
Thanks for the suggestion. I tried that but still no dice. Exact same failure as before. I've also tried disabling the onboard SCSI controller (which isn't being used) in case that was interfering, but that made no difference either.
