qubes on an x260 with skylake cpu…

[Holger Levsen]

Hi,

so I'm still trying to run Qubes properly on an Thinkpad x260 with i5
skylake CPU. Qubes 3.1 installed nicely, but the graphics is completly
broken after suspend and battery life is less than half of what it
should be.

kernel 4.1.13-9.pvops.qubes works nicely, but has those suspend and battery
life issues.

kernel 4.4.10-9.pvops.qubes doesnt boot. (Goes black after "loading
initramfs" immediatly… even with debug…)

kernel 4.5.5-300.fc24 doent boot, same symptoms.

I'm also upgrade to xen 4.6.1-15-56.fc20 but as xen 4.6.0 it shows the same
symptons with kernels 4.1.13, 4.4.x and 4.5.x, so I assume this is actually
a kernel and not a xen issue.

I've tried Mareks .iso image from
https://github.com/QubesOS/qubes-issues/issues/1807 but that also showed the
same symptoms.

So I guess I'll be forced to build my own 4.5 kernel (havent done this
on fedora since a very very long time, so I would rather like to avoid
this) with the half baken patch from the
http://xen.markmail.org/message/44kawmueeecmzbcj thread
or does anyone have other suggestions I can try?

Does rawhide have a 4.6 kernel already?

Any other suggestions?

If I've understood correctly, the mobile Skylake CPUs (only the mobile
CPUs, the desktop ones are not affected AFAIK) have in general issues
with sleep states in Linux such that the deepest states won't ever be
entered [1]. That might explain the battery issues you're seeing.

Hi,

I wrote this in a hurry and I guess it was clear what I ment but in case
