CD access panic on 5.2RC2 (similar to panic before for audio/data CD access)

I am currently running the following:

FreeBSD the-saint 5.2-RC2 FreeBSD 5.2-RC2 #0: Sat Mar 13 20:37:02 EST 2004     kaarthik_at_the-saint:/usr/src/sys/i386/compile/THE-SAINT  i386

When I try to play audio CDs, on every fourth CD the system panics.
>From the archives, I find the stacktrace (it is attached below) is the
same as the ones people have seen when trying to access a data CD
after accessing an audio CD. I checked the archives and the last mail
on this topic seems to be from Dec 2003 (subject: "panic in
devstat_remove_entry"), where someone confirmed that they still have
this panic. I dont see this as being fixed, atleast not in the
-current archives. Has this been fixed in 5.2.1? Would an upgrade
solve this for me? Thanks..

The stacktrace is (copied by hand, so possibility of a typo exists):

P.S: Is there a two-way newsgroup for this group? I am accessing
newsgroup mailing.freebsd.current on giganews, but that doesnt seem to
be two-way, ie I cant post to the newsgroup and see the mail on the
mailing list.
