Package: src:linux Version: 5.2.9-2 Severity: important Tags: patch upstream
Dear Maintainer, Linux 5.2 kernels contain a bug that causes short graphics freezes when using the i915 driver on certain Intel GPUs. The issue was originally reported here: https://bugzilla.kernel.org/show_bug.cgi?id=204183 A patch for 5.2 is available here: https://patchwork.freedesktop.org/series/63774/#rev4 This patch will likely be included in kernel 5.3, but 5.2 and possibly older kernels are also affected. Please consider adding this patch to 5.2 until it arrives in a stable kernel. As a temporary workaround, it's possible to disable PSR (Panel Self Refresh) by adding i915.enable_psr=0 to the kernel command line. There may be higher power consumption or other consequences. Thanks!
