Nothing obvious from the log, the only issue I see is [ 2.020663] irq 45: nobody cared (try booting with the "irqpoll" option) [ 2.020667] CPU: 3 PID: 0 Comm: swapper/3 Not tainted 5.4.0-rc3+ #1 [ 2.020671] Hardware name: Dell Inc. Vostro 3681/06CV2N, BIOS 0.6.13 10/07/2019 [ 2.020673] Call Trace: [ 2.020679] <IRQ> [ 2.020683] dump_stack+0x63/0x85 [ 2.020685] __report_bad_irq+0x35/0xc0 [ 2.020687] note_interrupt+0x24b/0x2a0 [ 2.020689] handle_irq_event_percpu+0x54/0x80 [ 2.020690] handle_irq_event+0x3b/0x60 [ 2.020691] handle_fasteoi_irq+0x7c/0x130 [ 2.020693] do_IRQ+0x54/0xe0 [ 2.020695] common_interrupt+0xf/0xf [ 2.020696] </IRQ> but that's in both logs. Did you try this with the latest drm-tip and then with the patch reverted on top top of that? Is it 100% reproducible? Do you get an FB console? (booting to bootlevel 3 adding "3" to the kernel parameters).</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
