Panic on boot with r353298 (last known working r35295)

Hey, just a heads up that on a Lenovo A485 (AMD Ryzen processor), 
r353298 panics somewhat late in the boot process. r352925 is my 
last known working build.
I am building GENERIC-NODEBUG.

Sadly my pulse is shaky and I can't properly read the picture I 
took, it appears to say:

Fatal trap 32: page fault while in kernel mode
*something, something*
fault mode = supervisor read data, page not present

Will try to get more details and a proper dump when I have some 
time off (hopefully later today), just thought I'd warn before.
