>Description:
      After build of kernel with 'device atapicam', booting to single user mode results in a hang at:
"Enter full pathname of shell or RETURN for /bin/sh:"

No characters appear as you type and Return does nothing.  The keyboard still works as I can use scroll lock to review the boot messages, and CTRL-ALT-DEL to reboot.

When device atapicam is removed from the kernel, I can boot to single user mode and continue to installword.

However, I still cannot drop to single user with 'shutdown now'.  It hangs at the same spot.  Again, CTRL-ALT-DEL can reboot gracefully.

Problem came only after cvsup from 5.4-RC3 to 5.4-RELEASE.  5.4-RELEASE discs not available yet.  Kernel built with same options from 5.4-RC3 or earlier has no problem.
>How-To-Repeat:
      I installed with 5.4-RC3 discs, build and installed world and custom (and working) kernel using procedure in UPDATING.  On May 6,2005, cvsup to 5.4-RELEASE.  Build and install using same kernel config file.

Same problem occurs on another computer after cvsup from 5.4-RC3 to 5.4-RELEASE.  Have repeatedly upgraded with similar procedure and using atapicam starting from 5.2.1.
>Fix:
      To boot to single user:  remove 'device atapicam'.
To drop to single user: ???.
