On a Gentoo guest in Virtualbox I rebuilt a kernel, which after rebuilding, makes Virtualbox crash. Sem kernel config built with binutil <2.27 works fine. Reproducible: Always Steps to Reproduce: 1. Build kernel with efi stub 2. boot kernel via efi stub Actual Results: Crashing kernel Expected Results: Booting kernel After some time I had to recreate the kernel to include initramfs changes. Surprisingly the kernel did not boot but Virtualbox crashed. First I changed Virtualbox versions, without any effect. I tried a different kernel version with same config, still crashing. I then took the time to switch back to binutils-2.26, make clean && make both kernel versions again. And they are working as expected. I then tried the crashing kernel on a native platform and it indeed leads to a reset of the platform. Kernel Versions are: 3.16.37/39 and 3.18.45.
I just tested this with 4.1.36. binutils-2.26, kernel works in Virtualbox and on native platform. binutils-2.27, kernel crashes in Virtualbox and on native platform. I guess, I could possibly check more native platforms. Sicne the behavior is consistent over at least 3 kernel versions, I think this is really related to binutils-2.27.
Please add emerge --info.

can you describe how to reproduce this ? does it only crash w/vbox ? binutils-2.28 is in the tree now ...
(In reply to SpanKY from comment #4) > can you describe how to reproduce this ? does it only crash w/vbox ? > > binutils-2.28 is in the tree now ... I switched back to 2.26.x for the time being. I did try using the very same kernel on native hardware. I used the stub by exec'ing the kernel from the UEFI shell (both vbox/native) and on native hardware an immediate reset occured. As I noted, I tried different kernels to see if it was the stub loader's code, but the behavior was reproduceable over various kernels. I'll see if I can check 2.28 later tonight and report back.
I'll be damned. I built kernel images with binutils 2.26/2.27/2.28. All 3 images work under Vbox now. However, while staying with older binutils I kept upgrading the rest of the system constantly. Is it possible, that this was caused by a specific combination of different packages and their respective versions?
(In reply to Sven E. from comment #6) it very much could be a comedy of errors. if things are working together now, i'd just call it fixed and move on to other bugs :).
