Title:
pmd_set_huge: Cannot satisfy [mem 0xf0000000-0xf0200000] with a huge-
page mapping due to MTRR override
Status in linux package in Ubuntu:
Triaged
Bug description:
This is logged with the 4.8 kernels
4.8.0.7-13 actualy used, from the unstable ppa
Its an upstream problem, as such error is found all over the distros.
Can not say if its due to incompatible hardware, buggy bios or
lintian/systemd/acpi/... reason(s) nor if a booting setting is
required
note: this does not semms affecting the system (in my case at least).
The hardware is quite old, and the bios is no more upgradable.

" Drivers should make a mapping request aligned to a single MTRR entry
when the range is covered by MTRRs. "
