https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D264267 --- Comment #1 from Michael Baptist <mbaptist.opensource@gmail.com> --- A little more background the Azure EFI firmware has a free memory region at 0x200000, however for larger kernels the EFI copy will write into EFI memory and cause a fault. The before we trampoline the new EFI_COPY_DISABLE option will allow us to s= kip copying and sets up page tables for 4G of physical memory (I think) and sho= uld map in our kernel in place. This all seems to work fine. Once the Kenrnel is loaded and we run sysinit I can see the trademark, copyright, an <BOOT> (boottag) stuff printing and then the console dies. I assume those sysinit functions are not the problem but others might be causing it to crash in so= me way. (Maybe vm subsystem code?) --=20 You are receiving this mail because: You are the assignee for the bug.=
