When using Intel Skylake Graphics the dmesg logs send the message "i915_bpo 0000:00:02.0: BAR 6: [??? 0x00000000 flags 0x2] has bogus alignment" every couple of minutes.

I'm suffering too, on a HP x360 4109NA running up to date 16.04.

Status changed to 'Confirmed' because the bug affects multiple users.

[Alberto Salvia Novella (es20490446e)]

Please, do the following:

1. In the Terminal application, enter "sudo apt install iucode-tool".
2. If after that you still experience this bug, upgrade your computer BIOS.
3. If after upgrading the BIOS you still experience this bug, set this report status back to "confirmed".

Thank you.

I have had iucode-tool installed from the start. My BIOS is the latest available (F42).
