Comment 70 for bug 411294

I think I am seeing this problem also on an old ThinkPad T41 with RV250 on resume. I first see this:
radeon 0000:01:00.0: PCI INT A -> Link[LNKA] -> GSI 11 (level, low) -> IRQ 11
Oct 29 10:02:08 t41 kernel: [drm] GPU reset succeed (RBBM_STATUS=0x00000140)
Oct 29 10:02:08 t41 kernel: [drm] radeon: cp idle (0x02000000)
Oct 29 10:02:08 t41 kernel: [drm] radeon: ring at 0x00000000D0000000
Oct 29 10:02:08 t41 kernel: [drm:r100_ring_test] *ERROR* radeon: ring test failed (sracth(0x15E4)=0xCAFEDEAD)
Oct 29 10:02:08 t41 kernel: [drm:r100_cp_init] *ERROR* radeon: cp isn't working (-22).
Oct 29 10:02:08 t41 kernel: radeon 0000:01:00.0: failled initializing CP (-22).
Oct 29 10:02:08 t41 kernel: [drm] LVDS-13: set mode 1400x1050 1e

After which I get a continuous stream of these errors:
[drm:radeon_cs_ioctl] *ERROR* Faild to schedule IB !
[drm:radeon_ib_schedule] *ERROR* radeon: couldn't schedule IB(7).

My display is garbled, but I can switch to a VT. Would it help if I collected the debug data also?
