..... (ahci-related panic)

As a note I have a machine here with /several /SATA-attached SSDs on 
ahci and they get quite-heavy load as one ZFS mirror set is in fact what 
the box boots and runs from:

ahci0: <Intel Cannon Lake AHCI SATA controller> port

ahcich1: <AHCI channel> at channel 1 on ahci0
ahcich2: <AHCI channel> at channel 2 on ahci0

ahcich4: <AHCI channel> at channel 4 on ahci0
ahcich5: <AHCI channel> at channel 5 on ahci0
ahcich6: <AHCI channel> at channel 6 on ahci0
ahcich7: <AHCI channel> at channel 7 on ahci0
ahciem0: <AHCI enclosure management bridge> on ahci0
