Hi, I have linux 2.4.25 + swsusp 2.0.0.10 on compaq evo 1015 (ati radeon IGP 320M) and I recently installed the dri trunk of xfree86-xserver recompiling all sources from scratch. This way I got finally dri working but when I tried to hibernate my laptop (note that hibernation works with xfree 4.3.0 of debian unstable), though the suspension went fine apparently, on resuming after a while it was reading caches the laptop rebooted automatically... :( any hints, tips?
thx Cristiano
The fundamental issue is that AGP drivers have no PM or broken PM (Radeon).
Superficial look at readeon 2.6 driver reveals that interrupts and DMA is not handled. I do not yet understand how AGP memory is managed.
2.6.3 has the known issue that non-suspend-media drivers are resumed _prior_ to reading image 2, explaining early resets.
2.4 Resumes drivers _after_ reading image 2 as it should be.
Reason according to Nigel is that he has to find a way to resume part of the device tree in 2.6.
AGP info is available here. http://www.intel.com/technology/agp/toverview.htm
Any chance to get some datasheets?
Regards Michael
