Bug Description

System freezes completely, but not all at once. Some windows become unresponsive first, then eventually system is totally unresponsive.

Managed to trigger what appears to be a similar issue when testing using Linux 4.17-rc1, but bug reporter did not come up that time.

This issue appears to be an upstream bug, since you tested the latest upstream kernel. Would it be possible for you to open an upstream bug report[0]? That will allow the upstream Developers to examine the issue, and may provide a quicker resolution to the bug.

Please follow the instructions on the wiki page[0]. The first step is to email the appropriate mailing list. If no response is received, then a bug may be opened on bugzilla.kernel.org.

Once this bug is reported upstream, please add the tag: 'kernel-bug-reported-upstream'.

Just an update, testing on 4.17-rc2 now. The issue doesn't come up that often, so I'll give it a few days to a week just in case.

Issue still occurring in 4.17-rc2.

Which mailing list should I email with the bug report? I have no idea what the actual cause of this issue is.
