Dear Larry, We are currently investigating the causes of the WARNING messages you=20 mentioned in this log: [ 4.141284] ------------[ cut here ]------------ [ 4.141285] alg: self-tests for sha1 using sha1-padlock-nano failed=20 (rc=3D-22) [ 4.141302] WARNING: CPU: 2 PID: 657 at crypto/testmgr.c:5865=20 alg_test.cold+0xb7/0xe0 Regarding the inability to adjust the laptop backlight brightness, we=20 believe this issue is unlikely related to the CPU itself. It is=20 recommended to contact the laptop manufacturer to confirm whether the=20 device supports backlight brightness adjustment and inquire about=20 specific configuration methods, such as installing specific EC=20 controller drivers or updating graphics card drivers.
