Version: freebsd-utils/10.1~svn273304-1
Severity: important

I started the daily dist-upgrade on my Sid running kfreebsd-i386 system
about a day ago. It still hangs here:

I currently have no idea if this is a bug in camcontrol itself or if
grub-pc's postinst is calling it with the wrong arguments. Feel free to
reassign that bug as needed.

I still haven't killed that process yet, so I may be able to get some
more debug information from the affected process. (Instructions what
else to get would be helpful in this case.)
