my un-dead dvd writer: "/dev/sr0 is locked via O_EXCL" [SOLVED]

i tried burning an image and the progress bar got stuck at 16%.  i then closed the program using the gui but it hung.  i then issued a "killall xfburn" which completed.  however the drive is still spinning away and becoming quite warm. i have a new and confusing message:

[au@arroyo1 ~]$ ps aux|grep sr0
root      2247  0.0  0.0  17780  1220 ?        S    Aug25   0:02 hald-addon-storage: no polling because /dev/sr0 is locked via O_EXCL
au       20456  0.0  0.0   7772   940 pts/1    R+   22:26   0:00 grep sr0

what on earth does this mean?
thanks

I read one forum (http://www.nabble.com/Hald-polling-devi … 24991.html) that seemed to indicate this type of issue was a problem with hal. I noticed in my system update last night that there was a new version of hal, so maybe try installing it and seeing if that helps at all.

thats possible, but ill never know since it ended up getting so bad that when i rebooted, i couldnt even login anymore (the passwords for all users were completely inaccessible).  no choice but to wipe everything.  the strangest thing was that i had some music files stored on an lvm volume, which was recognized by the live cd that i used to reinstall arch on A COMPLETELY NEW DISK, however when i experimented with mounting this old volume on the root partition of the new disk, /arch/setup crashed (the only warning that i had was executing vi on /etc/rc.conf during configuration and getting an empty file).  the location of /etc/rc.conf was given as /mnt/etc/rc,conf so apparently even chrooting failed in /arch/setup. 

the following statements are commonly appreciated by morons:

"it takes a village"
"cancer will be solved"
"no new taxes"
"COMPROMISED LVM2 VOLUMES ARE POISON!"

one of these statements is true, heheh <winces in pain>

so believe it or not i believe that the answer was PSU replacement.  after trying unsuccessfully in lists with lots of systems people, i eliminated all hardware components except the PSU by trial and error.
