If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit b75fcda760b8672326c2b5aca9108dffbeaf2730 Author: Prashant Malani <pmalani@xxxxxxxxxxxx> Date: Tue Sep 28 03:19:32 2021 -0700 platform/x86: intel_scu_ipc: Increase virtual timeout to 10s [ Upstream commit 5c02b581ce84eea240d25c8318a1f65133a04415 ] Commit a7d53dbbc70a ("platform/x86: intel_scu_ipc: Increase virtual timeout from 3 to 5 seconds") states that the recommended timeout range is 5-10 seconds. Adjust the timeout value to the higher of those i.e 10 seconds, to account for situations where the 5 seconds is insufficient for disconnect command success.
