Bug#956891: i915 intel VGA controller: null pointer dereference in i915_active_acquire()
Package: src:linux
Version: 5.4.19-1
Severity: important
Tags: upstream
Dear maintainers,
thanks for your hard work with this package, really appreciated.
I would like to report a kernel crash related to the i915 intel VGA controller.
The issue happens with both 5.4.0-3-amd64 and 5.4.0-4-amd64, specially
when I'm using videconferencing (google meet in both Chromium and Firefox).
Here is the trace I was able to see:
