I upgraded my Debian system today and at kernel version 6.12.90 the problem can still be reproduced. And then I decided to upgrade my laptop's firmware. After upgrading to `0.1.46` firmware the problem seemed to be disappear. Although the latest firmware version (as of 2026-05-25) is 0.1.49, I went through 0.1.45 -> 0.1.46 -> 0.1.47 -> 0.1.48 upgrade path and then stay at 0.1.48 for now.
To work around previous upgrade failure I changed "Security -> UEFI BIOS Update Option -> Flash BIOS Updating by End-Users" to "On". Previously the "Secure RollBack Prevention" option in the same BIOS setting page was set to "Off" and I also changed it to "On". The way I upgraded my firmware: first find out the device UUID of the firmware by looking into: CLI> sudo fwupdmgr get-devices Then find out available firmware versions: CLI> sudo fwupdmgr get-releases 18cced7e-d108-41c4-9189-b0355c41450d Then applied the firmware upgrade (and went through 0.1.45 -> 0.1.46 -> 0.1.47 -> 0.1.48) CLI> sudo fwupdmgr install 18cced7e-d108-41c4-9189-b0355c41450d 0.1.46 Post the result here so that it may help other people.
