bodhi,

I guess they were fixed, I upgraded the kernel to 4.19.58 to be in line with Debian 10. After booting the kernel and ramdisk, I got dumped into the Debian installer, but I'm failing steps in the install process.

Got it working with Debian 10 (kernel 4.19.58), here is the full console from boot to login:
