Problem: FreeBSD 8.1-STABLE/amd64 crashes with radeon and radeonhd in
different, weird ways.
I figured out when changing a box from a single-core hardware platform
with FBSD 8.1-STABLE/amd64 UP kernel to a SMP kernel with a dul core CPU
that a former 'stble' arragemnet of a AMD HD4830 and radeon/radeonhd
driver became instable. Whenever I leave an X11 session returning to
xdm's login screen, the box freezes and only reset can bring it back to
life.
My lab's box is still as reported months ago of the same problemacy. The
box runs also FreeBSD 8.1-STABLE/amd64 and has a SMP kernel running. The
graphics adaptor was a HD4670, now a HD4770. Exiting a session and
returning to the login screen is the same, the box freezes.
Also very strange is the behaviour when trying to use HAL and DBUS as
introduced with the newer X11 port revision. With both radeon and
radeonhd the box starts well, presents the login screen and is network
accessible. But whenever I activate HAL and DBUS (with a copy of
X11/xorg.conf of my private box and configuration which works which the
same OS revision) the box dies immediately and freezes with a black
screen when X11 tries to come up (the xdm in this case).
Even with identical configs and DRI/EXA turned off explicitely the box
freezes if hal and dbus are enabled (config is, as I mentioned, adjusted
to work with dbus and hal as it does on my private box).
Regards,
Oliver
