After "kill -9 <pid of mountall>" everything seems to work fine

Could you add --debug to the exec line in /etc/init/mountall.conf then attach /var/log/boot.log

Looks like mountall successfully mounts all filesystems in both cases. I wonder if this isn't bug #559761 - when mountall is consuming CPU, what is it doing? (strace/gdb)

Thanks, that indeed appears to be a duplicate of bug #559761 then.
