Comment 23 for bug 1950436

Same bug in Linux Mint 20.3 Una on Tuxedo Aura15 Gen1. After upgrading to kernel 5.13.0-25-generic I get white noise instead of login-screen after waking up from suspend or after screen was turned off due to power management. This is also present in 5.13.0-27-generic. This has happened also one time directly after booting, akin to description of similar/same(?) bug #1952155 here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1952155
Booting in older kernel resolves problem (5.11.0-46-generic)
