Shortly after installing Solus 1.2 stable on a new computer, I noticed that systemd-journal was using ~12% of my cpu(100% of a single core) writing several thousand items/second to logs. A system update using "sudo eopkg up" and the 4.7 kernel did not appear to resolve the issue.

Here are the log entries, these 2 lines are repeated ~2k times/second while the computer is turned on.

ACPI Error: [PGRT] Namespace lookup failure, AE_NOT_FOUND (20150930/psargs-359)
ACPI Error: Method parse/execution failed [\_GPE._L6F] (Node ffff8808554c22d0), AE_NOT_FOUND (20150930/psparse-542)

I was able to locate a similar report at this link https://bugzilla.kernel.org/show_bug.cgi?id=105491 which I think may be related. The motherboard in question is an AsRock Z170M Extreme4 with the latest version p1.70(http://www.asrock.com/mb/Intel/Z170M%20Extreme4/index.us.asp?cat=Download&os=BIOS) of the BIOS. Unfortunately the newer versions of BIOS mentioned in the bugzilla.kernel.org link are not available for this specific model. I suspect that the root problem is in the BIOS, but am not sure and reporting here as requested. Thanks.

EDIT: I was able to replicate this same issue using the latest linux mint 18 using a live usb, so this issue is not specific to Solus.
