Created attachment 278727 [details] Screenshot - Kernel Panic Hi, I've been facing a segfault on the kernel for 4.15+ ..

Can you update your BIOS and try the latest upstream kernel from git? If you don't know how, ask questions. Thx.
Sorry, this bug has since been resolved in newer kernels. Currently running a stable 4.20
I'm sorry, but this bug has been fixed in later kernels. Running a stable 4.20 right now https://space-barclicker.com
