After that there is constant flood of messages from 'EQ overflow continuing'
This is essentially the same backtrace that you already reported in
#686474, sorry for not having followed up on that. It seems that this
is triggered by enabling the "GLXVBlank" option in xorg.conf, and that
there is a fix in version 1.0.3ยน. I'll see to include this in the
Debian package.
OK, I'll disable it and try to play for some time to see if problems
stops.
