Created attachment 146009 [details] GPU crash dump Recently, my laptop has started freezing the display for around 5 seconds. This is extremely frustrating as I've owned this laptop for more than 3 years now and this has not happened before. Why is the software getting worse? Anyway, after such an event, the following appears in dmesg: [ 8463.247217] i915 0000:00:02.0: GPU HANG: ecode 9:0:0x00000000, hang on rcs0 [ 8463.247218] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace. [ 8463.247218] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel [ 8463.247219] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue. [ 8463.247219] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it. [ 8463.247220] [drm] GPU crash dump saved to /sys/class/drm/card0/error [ 8463.248228] i915 0000:00:02.0: Resetting rcs0 for hang on rcs0 This happened again shortly after, with just the below in dmesg: [ 8685.113116] i915 0000:00:02.0: Resetting rcs0 for hang on rcs0 I've attached the crash dump as requested in the dmesg output. I'm running Archlinux on a Thinkpad T460. The kernel version is: 5.3.12-arch1-1. I have a monitor attached on the display port. This is the lspci output for my graphics card: 00:02.0 VGA compatible controller: Intel Corporation Skylake GT2 [HD Graphics 520] (rev 07) (prog-if 00 [VGA controller]) Subsystem: Lenovo Skylake GT2 [HD Graphics 520] Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx+ Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 0 Interrupt: pin A routed to IRQ 128 Region 0: Memory at e0000000 (64-bit, non-prefetchable) [size=16M] Region 2: Memory at c0000000 (64-bit, prefetchable) [size=512M] Region 4: I/O ports at e000 [size=64] [virtual] Expansion ROM at 000c0000 [disabled] [size=128K] Capabilities: <access denied> Kernel driver in use: i915 Kernel modules: i915 Please let me know if I can help or provide further information as I would like to see this fixed.

Can you try to reproduce the issue with drm-tip kernel? (https://cgit.freedesktop.org/drm-tip)
