[Bug 635439] Re: No UEFI boot on Dell Precision M4500
On my system, also labelled as a Dell Precision M4500 although it's a development system so could be a bit different, GRUB shows the set_virtual_address_map function as being at address 0xbb65d280. I wouldn't be surprised if my memory map was a bit different from yours, but this is still in the bottom 4GB of memory rather than way up at the top. I notice this in your log, which is odd and suggests a problem: [0.00] Kernel-defined memdesc doesn't match the one from EFI! I'll look into this more when I can. -- No UEFI boot on Dell Precision M4500 https://bugs.launchpad.net/bugs/635439 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Maybe this will shed some light on it. ;) I happen to have a suitable docking station for my Precision M4500.

[0.279212] RIP [cccafed0] 0xcccafed0 Thanks, that's interesting. Sort of similar to what Mario found on a different machine, although the symptom is very slightly different. I think it will be easiest to debug this when I can iteratively install new test kernels and GRUB images on my machine and observe the output. In the meantime, I can confirm that the fault is at arch/x86/kernel/efi.c:167, matching Mario's log: status = efi_call_phys4(efi_phys.set_virtual_address_map, memory_map_size, descriptor_size, descriptor_version, virtual_map); It is interesting that 0xcccafed0 is way up in the kernel module mapping area, not in anything that seems a plausible physical address, and it doesn't match anything in the EFI memory map either (which seems to tentatively rule out the idea that GRUB might just be constructing the E820 map wrongly). I would have expected this function to be in one of the EfiRuntimeServicesCode ranges, namely: [0.00] EFI: mem355: type=5, attr=0x800f, range=[0xcf5df000-0xcf636000) (0MB) [0.00] EFI: mem356: type=5, attr=0x800f, range=[0xcf636000-0xcf65f000) (0MB) I smell a rat, but as yet I'm not sure what kind. In-kernel memory corruption, or are we failing to mark the EFI system table as reserved so it gets overwritten? Or something else?

On my machine takes a second or 15 between the BIOS screen disappearing and (for now) Windows 7 boot screen appearing when booting normally. In between there seems to be some hard disk activity, as if the BIOS scans all partitions for boot loaders. Yes, I suspect that's pretty much what it's doing.
