Title:
Intel GPU Hangs : random screen freezing w/ Ubuntu 20.04 (Linux 5.4)
i915_active_acquire
Status in linux package in Ubuntu:
Invalid
Status in linux source package in Focal:
Fix Committed
Bug description:
SRU Justification:
[Impact]
Users are experiencing a frequent NULL pointer dereference crash in
i915_active_acquire when using kms, which is used by default.
[Fix]
The fix is a cherry pick from upstream which was supposed to be backported to
5.4 by upstream, but was neglected. The fix has a subsequent Fixes patch to
resolve some uninitialized pointer usage.
[Test]
Verified by multiple bug reporters.
[Regression Potential]
Medium. Although there are a lot of lines added, they're mostly boilerplate,
and this patch is confirmed by multiple users to fix a crash.
