Hey Dann, thanks a lot for the thorough analysis, the reasoning makes sense. I'm just a bit sceptical because we use tinycore 9.x at the moment, with kernel 4.14, which includes the patch for the kernel panic you mentioned, it was just moved under drivers/firmware/efi/efi-bgrt.c, so I'm not sure that could be the explanation for the error. We're in the process of upgrading tinycore to 10.x which will bring in kernel 4.19, although I don't see any substantial changes in he efi-bgrt management. I wonder if there was a regression at some point, but it's unlikely. I'll let you know how it goes with tinycore 10.x, in the meantime if you have any other ideas or advice, please let me know. Thanks!
