            Bug ID: 273292
           Summary: ahcich:
           Product: Base System
           Version: 13.2-RELEASE
          Hardware: Any
                OS: Any

Full OS release: 13.2-RELEASE-p2

Recently getting numerous ahcich related errors, some related to external SATA
drives and latest apparently related to internal SATA drive.

External:
ada3:ahcich0:0:0:0): CAM status: Uncorrectable parity/CRC error
(ada3:ahcich0:0:0:0): Retrying command, 3 more tries remain
(ada3:ahcich0:0:0:0): WRITE_DMA48. ACB: 35 00 c0 15 67 40 1b 00 00 00 00 08
(ada3:ahcich0:0:0:0): CAM status: Uncorrectable parity/CRC error
(ada3:ahcich0:0:0:0): Retrying command, 3 more tries remain

In some cases, the above error stream would end with an automatic
HDD detachment.
Replacing cable, detach/re-attach cable, use different HDD in enclosure: none
of these make any difference. These usually occur during large scale file
copying.


Internal:
(aprobe0:ahcich3:0:0:0): CAM status: Uncorrectable parity/CRC error
(aprobe0:ahcich3:0:0:0): Error 5, Retry was blocked

    [ada0: WD4500HLHX-01JJPV0]
This just recently "popped up out of nowhere" with drive unattached and not
being used.

Smart tests don't indicate any particular errors.

Not been a problem under FBSD-13.1 or FBSD-12.4.
