We have 6.8.2rc1 in Mandrakelinux Cooker. Since updating my laptop to this release, I have some issues with X. 1) I normally use XFCE. The desktop and the apps in my .xinitrc partially load, but the XFCE splashscreen doesn't leave the screen and the cpu apparently goes very high (laptop fan running). Mouse still moves, but is displaying the hourglass. 2) Trying to go to a VT success, but trying to get back to X shows a corrupted desktop display (top 1/8 or so of the screen is corrupted). No mouse. X is at 98% cpu logging in from anther machine, and I'm unable to kill it as root, not shutdwn the machine. Ctl-Alt-SysReq-B does work. Last lines of Xorg.0.log are: (WW) Open APM failed (/dev/apm_bios) (No such file or directory) (II) RADEON(0): [RESUME] Attempting to re-init Radeon hardware.

does the DynamicClocks option (documented in the radeon manpage) have any effect?
Tried DynamicClocks: (II) RADEON(0): Dynamic Clock Scaling Enabled No difference in bahvior. Switching to VT2 and back again gives a corrupted display and no mouse. Can't get back to a VT to reboot or kill X. Up until we moved from 6.8.1 to 6.8.2, things were ok.
I am using the Slackware-current release package x11-6.8.2-i486-1. the problem persists. Any screen resolution change puts X into an ioctl that takes 99% cpu. this happens when a game changes res, or when switching from a vesa-vt back to X. It all worked fine in an earlier version of Xorg. This problem is really painful, as it requires a reboot. X cannot be killed. X can be sigstop'd which does stop it... I even tried an older version of linux (2.6.3 instead of 2.6.11.7) which had the same exact symptoms.
Do you think that this is the same bug as #4324?
Possibly, I no longer have that machine now. I ended up using the vesa driver for the rest of that cooker development period.
I would ask if disabling DRI makes any difference (see #1717), but since you don't have the hardware any more I'll just close the report.
