Hi.
I would really appreciate if you could point me on some sort of manual that describes how to properly run [2] on Ubuntu? Should I run the whole kernel or just some modules? Is there any way to build only requires modules?
The whole kernel. See https://wiki.ubuntu.com/KernelTeam/GitKernelBuild for a starting point; please use the drm-intel-nightly branch in our tree instead of Linus' tree.
Thank you so much for that link. I've created a bug report about original suspend/resume issue: https://bugs.freedesktop.org/show_bug.cgi?id=76301.
I was able to build drm-intel-nightly kernel using instructions from above link but unfortunately I run into issues: - It looks like I get unsigned kernel modules and this prevents proper debug output, hopefully I would be able to resolve this on my own but unfortunately I won't be able to provide useful dmesg just yet. - The drm-intel-nightly '6e052fec0cc204f4d2a0f71f45c0363971ad10dc' kernel hangs during boot on my aforementioned hardware. I've tried several times and mostly I get black screen. But couple of times I got some error output that stated something about softlock and lost interrupts - and it was sort of slowly printing those errors, once about 30 seconds. Unfortunately I do not have a hardcopy of that. The interesting thing is that when I add 'nomodeset' to boot parameters I'm able to successfully boot. I take it this is not expected and probably is a regression. I would appreciate if you could suggest course of action to debug this (and probably create another bugreport).
Thanks!
