on bug 111659
from Brad Campbell
I'm running out of ideas. I assume from the complete lack of interest I'm either putting this in the wrong place or everyone is concentrating on new hardware. Recap. This is happening on two separate and different machines. Both iMac, but one with a 6770M and one with a 6970M just to rule out hardware failure. Tried it with dpm off. That made it last a bit longer, but : [925997.946677] BUG: kernel NULL pointer dereference, address: 00000000000003f0 [925997.946690] #PF: supervisor write access in kernel mode [925997.946693] #PF: error_code(0x0002) - not-present page [925997.946695] PGD 0 P4D 0 [925997.946701] Oops: 0002 [#1] SMP [925997.946705] CPU: 3 PID: 26449 Comm: Xorg Not tainted 5.4.0-rc6-bkc1+ #4 [925997.946707] Hardware name: Apple Inc. iMac12,2/Mac-942B59F58194171B, BIOS 82.0.0.0.0 09/25/2018 [925997.946716] RIP: 0010:mutex_lock+0x14/0x30 [925997.946720] Code: e9 22 fd ff ff 90 be 02 00 00 00 e9 66 fb ff ff 66 0f 1f 44 00 00 53 48 89 fb e8 e7 ea ff ff 31 c0 65 48 8b 14 25 00 5d 01 00 <f0> 48 0f b1 13 75 02 5b c3 48 89 df 5b eb cd 0f 1f 00 66 2e 0f 1f [925997.946723] RSP: 0018:ffffc90000357a90 EFLAGS: 00010246 [925997.946726] RAX: 0000000000000000 RBX: 00000000000003f0 RCX: ffffc90000357b2f [925997.946729] RDX: ffff888264e38000 RSI: 0000000000000008 RDI: 00000000000003f0 [925997.946732] RBP: 0000000000000000 R08: 0000000000000001 R09: 0000000000000000 [925997.946734] R10: 0000000000000000 R11: 0000000000000000 R12: 0000000000000001 [925997.946737] R13: 00000000fffffffb R14: 00000000ffffffb9 R15: 0000000000000000 [925997.946741] FS: 00007f92358580c0(0000) GS:ffff888267b80000(0000) knlGS:0000000000000000 [925997.946743] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [925997.946746] CR2: 00000000000003f0 CR3: 0000000263d9b004 CR4: 00000000000606a0 [925997.946748] Call Trace: [925997.946761] drm_dp_dpcd_access+0x57/0xf0 [drm_kms_helper] [925997.946769] drm_dp_dpcd_write+0x21/0x90 [drm_kms_helper] [925997.946804] radeon_dp_set_tp+0x4f/0x80 [radeon] [925997.946832] radeon_dp_link_train+0x54f/0x570 [radeon] [925997.946862] radeon_atom_encoder_dpms_dig+0x21a/0x4e0 [radeon] [925997.946881] ?
