Hi,
i have a problem with my imx8m board.
I always get "Unable to handle kernel paging request at virtual address ffff000079c70000"
So i looked into the dmesg:

There is a not realistic size in the vmalloc. Although i use vmalloc=128M as kernel command line.
Where can i change this value?
Thank you!
