>Description:
After installation on hard drive the newly installed system randomly fails to complete booting.  It fails during device enumeration where it can't always locate the hard disk that it is booting from.  This is using a BIOS boot on an HP 6200 MT where UEFI booting has been disabled.

The failure to find the hard drive happens about 50% of the time. 
>How-To-Repeat:
Reboot system
>Fix:
Unknown, but the workaround it to attempting to reboot the system.

      Do you see a message that says WDCTL_RST failed?  If so, then
 this a known problem and there are already multiple PRs for it.
 If not, then you need to provide more information, such as a dmesg
 (at least a snippet showing the hard drive part) of when it fails
 and when it succeeds.  As is, you haven't provided enough information
 to even have any idea what the problem is, much less diagnose and
 repair it.

 No problem.  Just tell me where it writes the DMESG log to when it can=92t=
  find the disk it=92s booting up from.

 You can enter ddb and type 'dmesg'
