OpenBSD-2.7/i386 machine hangs up!

[Rakhesh Sasidharan <rakhesh_(_at_)_cse_(_dot_)_iitd_(_dot_)_ernet_(_dot_)_in>]

Somebody had raised this point earlier, and I had mentioned my case that
time also (in case of pre-2.7 snapshot).  My problem is thus:

OpenBSD-2.7/i386 hangs up on my machine for apparently no reason.  I would
be working, and the machine would just hang up.  More often that not, I
would be playing some songs, and even that stops -- so I suppose the whole
machine hangs.  I can't switch virtual screens, can't do anything.  (It's
a single home machine, and so I can't check to see if it is working
internally).

Has there been any discussions on this matter ?  When I had 2.6, things
were perfectly fine.  It didn't have this freezing/hanging problem.

My dmesg output is attached.  

Regards,
Rakhesh
