Ok, so my test is under gnome with metacity in composite mode. Using zsh (I think bash can do this also) balrog% for ((i=3D0 ; i < 5 ; i++ )) do firefox &;done So, I've launched 5 firefox and 10 xterms... Neither produce the hang. Sitting in drmwtq means that you are waiting on the rendering engine to catch up and send you an interrupt. Probably the best debugging that we are going to get is by: booting the system without starting X, kldload radeon and then set sysctl hw.dri.0.debug=3D1 and start X/KDE... trigger the lockup and send me the output of the debugging from /var/log/messages. robert. --=20 Robert Noland <rnoland@FreeBSD.org> FreeBSD --=-ULmA3AGwpHvbIWJny4M3 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.11 (FreeBSD) iEYEABECAAYFAknzRSQACgkQM4TrQ4qfRON4nQCffvMjRWIu2AX7WHuRCshkvWiD i5sAoIDtDIWOSkQGGVt2+i1kuhM1Pa1C =Mxyx -----END PGP SIGNATURE----- --=-ULmA3AGwpHvbIWJny4M3--
