As I have mentioned in my previous email, anytime I'm within the v5.8-rc* range of commits, running the kernel fails to get past a certain point at boot. init doesn't get executed, but SysRq keys work and I can reboot from there. Has this happened before? If there is an alternate method of getting the kernel debug logs for this (that doesn't involve a serial connection, as I don't have the equipment for that), I'm happy to get them for you.
