Any chance you cna disassemble it and perhaps also > run with acpi debug options on to figure out where it blows up? The weird thing here is that bare-metal on the same machine does work. And previous kernels did work as well. So I think we can assume the ACPI tables are ok. It could even be a red-herring. Well, likely is as booting with acpi=off does hang instead of crashing. Since I got no clue, I did what we always do when we are dumbfound, I went ahead and bisected 3.18..3.19-rc1. Unfortunately the very last kernel I build was something in between good and bad. Good as it did not crash exactly but bad as it did not come up in a usable state. So I would not be sure the claimed to be offending commit is right. Could be one in the range of: G * xen: use common page allocation function in p2m.c * xen: Delay remapping memory of pv-domain g * xen: Delay m2p_override initialization -> * xen: Delay invalidating extra memory B * x86: Introduce function to get pmd entry pointer (G) really good, (g) somewhat not bad, (B) bad, (->) claimed first broken. So it seems one of the delaying changes has a very bad effect on that Sharkbay. A bit odd since none of those sounds Intel/AMD geared. Could only be a different usage of memory (my AMD box has considerably more memory and also no CPU with GPU functionality as the Haswell). Jürgen, maybe some description that might trigger an idea for you...? -Stefan --- git bisect start # good: [b2776bf7149bddd1f4161f14f79520f17fc1d71d] Linux 3.18 git bisect good b2776bf7149bddd1f4161f14f79520f17fc1d71d #
