The first visible related error is memory allocation to store efi memory map just before we switch off BootServices, however simple switch to alternate memory does not chenge anything there, so it must be something more going o= n. My guess is that the best option still would be to hook up to gdb stub and = try to catch where we are blowing up and then we also know why exactly. Right n= ow we can only guess. --=20 You are receiving this mail because: You are the assignee for the bug.=
