The virtual console shows a kernel NULL pointer dereference at address 0. I run Arch Linux. The bug occurs even if I never run X. I can turn on the machine and immediately try to shut it down, and the same bug still occurs. This bug occurred since I upgraded linux 5.4.15.arch1-1 to 5.5.1.arch1-1. I now run linux 5.5.3.arch1-1 and the bug still exists. My graphics card is Gigabyte Radeon RX VEGA 56 GAMING OC 8G, connected to six monitors. A photo of the screen at shutdown is attached. I think these are the relevant lines for this bug: BUG: kernel NULL pointer dereference, address: 0 [...] RIP: 0010:queue_work_on+0x17/0x40 Code: fd ff ff 44 89 e0 5d 41 5c c3 [...] Call Trace: handle_hpd_rx_irq+0x26e/0x320 [amdgpu] ? _raw_spin_unlock_irq+0x1d/0x30 dm_irq_work_func+0x49/0x60 [amdgpu] process_one_work+0x1e1/0x3d0 [...] -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
