*** Bug 15971 has been marked as a duplicate of this bug. *** Hm, I tried a kernel with this patch reverted, but the problem persists. So i did a full bisect and still come to the same commit. I'm really puzzled. I don't think : 797fd5b9dad12a100c81b5782573a41259728cb1 drm/radeon/kms: r300 fix CS checker to allow zbuffer-only fastfill is the culprit, i will try to see if i can reproduce this issue. Can you test if rc6 is working or not ? tested and not working So to sumup rc5 is working and rc6 isn't ? yes that's it. oh my... I'm very sorry, but I should have not test the good one :-s rc6 is OK. (btw I tested 2.6.34 final but with no luck) Does suspend work with radeon.agpmode=-1 boot parameter ? Also please attach full kernel log after resume Created attachment 26436 [details]
dmesg after bad resume
the problem appears as soon as Xorg is started
with the boot parameter, the resume is ok Created attachment 26484 [details]
release agp bridge at suspend
Please test if attached patch fix the issue
compiled, tested and working. Thanks ! Thanks so much, this seems to have fixed the same issue on Mobility X700. I also had the same symptoms on 2.6.33, would the patch be applicable there as well? 2.6.34 up to rc6 was working though, like reported here. mobility x700 is pcie, so I suspect something different was the cause there. After looking at the code I think I can agree on that :) It got broken between 2.6.34 rc6 and rc7, and got fixed between master 20100523 and drm-next 20100524, but now that it works anyway I won't spend time on pinpointing it further. Thanks to whoever had their magic hands in there! I see this as well on my ThinkPad T42 with 2.6.34, while 2.6.33 works okay. I will try with the boot param of comment #10 and if that works with the patch from comment #14 May 31 14:46:53 shambhala kernel: [drm] Initialized radeon 2.3.0 20080528 for 0000:01:00.0 on minor 0 May 31 14:52:42 shambhala kernel: [drm:radeon_agp_init] *ERROR* Unable to acquire AGP: -16 May 31 14:52:42 shambhala kernel: [drm] GPU reset succeed (RBBM_STATUS=0x00000140) May 31 14:52:42 shambhala kernel: [drm] radeon: 1 quad pipes, 1 Z pipes initialized.

Thanks. Patch from comment #14 appears to work. I suggested it to the stable kernel team. Thanks. Fixed by commit 10b06122afcc78468bd1d009633cb71e528acdc5 . |
