Public bug reported: We have a set of ThinkPads (T410 and T540p) that are failing to boot (not locating their root fs device) with post-release kernels.
The AHCI adaptor (0000:00:1f.5) simply isn't visible in /sys/bus/pci/devices/ The problem is apparent in 4.2.0.25-30, and not in 4.2.0-16.19 If the SATA device mode is changed from AHCI to IDE emulation, then they reliably boot.
