I hate to be annoying but this time I have to be, because I don't like the idea
of not being able to use all the system memory Intel HD Graphics can
potentially claim and use.
Besides, the next stable kernel is closing in and it will be the second stable
Linux release I won't be able to use without crippling my hardware.
I ain't a Linux kernel expert but these messages seem bogus to me:
> [drm:i915_driver_load] *ERROR* Detected broken video BIOS with
> 262140/262144kB of video memory stolen.
> [drm:i915_driver_load] *ERROR* Disabling GEM. (try reducing stolen memory or

My BIOS is certainly not broken and all future Intel on-die GPUs may use up to
1.7GB(1) of the system RAM.

Intel makes up to 1.7GB of system memory available to graphics, as with its
previous-generation integrated graphics core, but there’s really no reason to
dedicate that much RAM in light of the GPU’s performance characteristics.

Well, these bios settings _are_ broken. They essentially steel 256MB of system
memory for the intel igd, which has two effects:
- Your usable system memory decreased by 256 (linux can't use this memory).
- You've reduced the memory available to the igd to zero (which then caused the
kernel oops later on).
So please change the bios settings to something sensible (32MB of so called
stolen space is enough) - linux will allocate anything it needs dynamically
anyway. This stolen space is only used to support certain special hw features
that absolutely require it.
I can't close this as "not a bug" due to not having sufficient bz permissions.
Can somebody else please take care of that?
