Bug#954817: linux-image-5.4.0-4-amd64: NULL pointer dereference in i915_active_acquire since Linux 5.4
Package: src:linux
Version: 5.4.19-1
Severity: important
Tags: patch
Dear Maintainer,
Since kernel 5.4.x I am getting crashes during some graphic rendering poccess like playing videos. I found the following patch might fix this problem.
The patch already got into kernel 5.5.x but still not into 5.4.x. Could you patch it into kernel 5.4.x? Or release the kernel 5.5 version? Thanks!
