Public bug reported: I'm left with a black screen after connecting a laptop into a thunderbolt dock.
The primary kernel error is logged "Failed to create MST payload for port", followed by a proper oops: "BUG: kernel NULL pointer dereference, address: 0000000000000008" The dock screens remain in power-save and the laptop screen remains black (usually it is blank when connected to dock). After unplugging from dock the laptop screen does not recover. I'm on 6.1-oem due to issues with AMD GPU not waking from sleep after the the HWE kernel update from 23.04 -> 22.04 kernel: amdgpu 0000:04:00.0: [drm] Failed to create MST payload for port 000000000a2b5491: -5 kernel: BUG: kernel NULL pointer dereference, address: 0000000000000008 kernel: #PF: supervisor read access in kernel mode kernel: #PF: error_code(0x0000) - not-present page kernel: PGD 0 P4D 0 kernel: Oops: 0000 [#1] PREEMPT SMP NOPTI kernel: CPU: 5 PID: 3215 Comm: gnome-shell Not tainted 6.1.0-1010-oem #10-Ubuntu kernel: Hardware name: LENOVO 82UD/LNVNB161216, BIOS JECN11WW(V1.04) 03/14/2022 kernel: RIP: 0010:drm_dp_add_payload_part2+0xce/0x100 [drm_display_helper] kernel: Code: e8 87 22 82 ff 44 89 f0 5b 41 5c 41 5d 41 5e 5d 31 d2 89 d1 89 d6 89 d7 41 89 d0 41 89 d1 e9 e9 80 08 d0 48 8b 80 58 05 00 0> kernel: RSP: 0018:ffffab9590f1b548 EFLAGS: 00010246 kernel: RAX: ffff8c77e8506000 RBX: ffff8c77e8506000 RCX: 0000000000000000 kernel: RDX: ffff8c7a1e8e7740 RSI: 0000000000000000 RDI: ffff8c77f0f14540 kernel: RBP: ffffab9590f1b568 R08: 0000000000000000 R09: 0000000000000000 kernel: R10: 0000000000000000 R11: 0000000000000000 R12: 0000000000000001 kernel: R13: ffff8c77f0f14000 R14: ffff8c780885a0c0 R15: 0000000000000006 kernel: FS: 00007f9dbdddb5c0(0000) GS:ffff8c7a5ff40000(0000) knlGS:0000000000000000 kernel: CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 kernel: CR2: 0000000000000008 CR3: 000000014b8d8000 CR4: 0000000000350ee0 kernel: Call Trace: kernel: <TASK> kernel: dm_helpers_dp_mst_send_payload_allocation+0x90/0xd0 [amdgpu] kernel: dc_link_allocate_mst_payload+0x1a9/0x350 [amdgpu] kernel: core_link_enable_stream+0x560/0x5e0 [amdgpu] kernel: apply_single_controller_ctx_to_hw+0x430/0x530 [amdgpu] kernel: ?
