Dear Larry,

We are currently investigating the causes of the WARNING messages you 
mentioned in this log:
[    4.141284] ------------[ cut here ]------------
[    4.141285] alg: self-tests for sha1 using sha1-padlock-nano failed 
(rc=-22)
[    4.141302] WARNING: CPU: 2 PID: 657 at crypto/testmgr.c:5865 
alg_test.cold+0xb7/0xe0

Regarding the inability to adjust the laptop backlight brightness, we 
believe this issue is unlikely related to the CPU itself. It is 
recommended to contact the laptop manufacturer to confirm whether the 
device supports backlight brightness adjustment and inquire about 
specific configuration methods, such as installing specific EC 
controller drivers or updating graphics card drivers.

BRs!
