restarting X fails and generates kernel panic on halt (was Re: Magic SysRq reboot (was Re: switching to proprietary ati radeon driver))
(Sorry for the long re-naming, but I fell the thread should get its
proper name as the issue evolves)

Thank you, I completely forgot about this one. Two issues though:
1. In an older discussion on Gentoo ML, it was suggested that the
SysRq procedure was normally designed for emergency situations only,
and not for regular usage. Currently my laptop would qualify for SysRq
shutdowns/reboots, but I would prefer to avoid using it for months.
2. Restarting X, such as when I log off Xfce and gdm restarts, will
fail. This is almost certainly caused by the fglrx driver/setup, to
which I switched these days. I also believe that this failure causes
the kernel panic on shutdowns/reboots after X failed to restart
(although panics can sometimes not happen).
On gdm restart, X will complain of "ddm" module already built in.
There are no such complaints during regular system boot, and initial
start-up of X.
Would anyone have ideas on how to get to the bottom of this issue?
Thank you
Liviu
