watchdog: BUG: soft lockup - CPU#1 stuck for 22s! [Web Content:11660]

[Jeremy Ong]

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.

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.

[Jeremy Ong (jeremyon)]

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.
