The stack output is strange,  that is why I move to printk,  and the old 
kernel looks good.

after some test, I fould first bad commit: 
[cfe2790b163acdc9c058a63bff310923e84a16b4] printk: move printk_info into 
separate array

Hi John,  there is printk-rework from you in v5.10-rc1,  could you check 
it ?

Thanks
