            Bug ID: 253067
           Summary: [PATCH] CF card not detected in Soekris net5501
           Product: Base System
           Version: 12.1-RELEASE
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: kern
          Assignee: bugs at FreeBSD.org
          Reporter: nick at van-laarhoven.org

CF card (Transcend Industrial) is no longer detected in Soekris net5501 and
boot therefore does not find a root disk to mount. Booting verbose *does* find
the disk and it boots as usual.

This setup worked on this platform on 11.3.

My solution is to increase the loop delay in ata-lowlevel, but I have no idea
whether this is a good solution. On detecting devices the loop is exitted, so
it should be fine.
