When the kernel DRM module is loaded, and I do a ALT-CTRL-KP- to change resolutions, the system locks up.
Apparently, the card is always reporting busy (drmCommandNone(DRM_RADEON_CP_IDLE) is always returning EBUSY).
This does not happen with the XFree4.2.1 release.
The system in question is a dual P3 1GHz machine, running 2.4.19, with a Radeon All-in-wonder 7500. This happens when I boot uniprocessor, as well.
I've been having this problem for several weeks.
