Hi,

I just discovered almost 100 of the following entries in my log:

[drm:intel_uncore_check_errors [i915]] *ERROR* Unclaimed register before interrupt

Those were accumulated in about 12 hours of operation. I also have one that says

i915 0000:00:02.0: BAR 6: [??? 0x00000000 flags 0x2] has bogus alignment

The above output was in the middle of the other type.

The "lspci -nnv" stanza for the i915 is:

00:02.0 VGA compatible controller [0300]: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller [8086:0416] (rev 06) (prog-if 00 [VGA controller]) Subsystem: Toshiba America Info Systems Device [1179:0002] Flags: bus master, fast devsel, latency 0, IRQ 31 Memory at e0000000 (64-bit, non-prefetchable) [size=4M] Memory at d0000000 (64-bit, prefetchable) [size=256M] I/O ports at 4000 [size=64] Expansion ROM at <unassigned> [disabled] Capabilities: <access denied> Kernel driver in use: i915 Kernel modules: i915

Please let me know of any further info that you need, or any diagnostics that I can add.

Thanks,

Larry
