--- Comment #34 from Alec Habig <ahabig at umn.edu> ---
I do: even with the current Fedora Kernel (4.17.19) and the latest Lenovo BIOS
(which got updated recently, presumably for spectre mitigation).  Just verified
this when booting this morning (accidentally chose the wrong kernel in grub).

I have made little progress on narrowing down which kernel features cause the
problem when enabled.  Your vanilla testing kernel works, the same version of
the fedora configured kernel does not.  But there's a lot of parameter space to
search, each "tweak/compile/boot/fail" iteration takes an hour, and this is the
laptop I use for actual work.  So slow progress :(
