https://bugzilla.kernel.org/show_bug.cgi?id=216198 Bug ID: 216198 Summary: uvd page faults on Radeon Product: Drivers Version: 2.5 Kernel Version: 5.15 Hardware: AMD OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: nutodafozo@freeweb.email Regression: No Created attachment 301322 --> https://bugzilla.kernel.org/attachment.cgi?id=301322&action=edit oops After upgrading ubuntu from 20.04 (had stock kernels 5.4, 5.8 and 5.13) to 22.04 with 5.15, I've started to experience page faults when hw acceleration on Radeon RX550 is working in Firefox. 2 times already in 5 days, same stacktraces / addresses of faulting instruction and the same zero $rbx register. I've had the same configuration for over a year, never had such oopses before on previous kernels. > [X77.269660] BUG: unable to handle page fault for address: fffffffffffffff8 > > ffffffff8111d4f0 <swake_up_locked>: > ffffffff8111d4f0: e8 fb 90 f6 ff call ffffffff810865f0 > <__fentry__> > ffffffff8111d4f5: 48 8b 57 08 mov 0x8(%rdi),%rdx > ffffffff8111d4f9: 48 8d 47 08 lea 0x8(%rdi),%rax > ffffffff8111d4fd: 48 39 c2 cmp %rax,%rdx > ffffffff8111d500: 74 2d je ffffffff8111d52f > <swake_up_locked+0x3f> > ffffffff8111d502: 55 push %rbp > ffffffff8111d503: 48 89 e5 mov %rsp,%rbp > ffffffff8111d506: 53 push %rbx > ffffffff8111d507: 48 8b 5f 08 mov 0x8(%rdi),%rbx > ffffffff8111d50b: 48 8b 7b f8 mov -0x8(%rbx),%rdi > !<<<<<<<<< > ffffffff8111d50f: e8 4c d6 fd ff call ffffffff810fab60 > <wake_up_process> > > void swake_up_locked(struct swait_queue_head *q) > { > struct swait_queue *curr; > if (list_empty(&q->task_list)) > return; > curr = list_first_entry(&q->task_list, typeof(*curr), task_list); > wake_up_process(curr->task); > list_del_init(&curr->task_list); > } -- You may reply to this email to add a comment.
