17 R5  was never tested or supported by Dell with Linux. DELL-Admin>

My kernel log is full of errors and warnings caused by bugs in the Alienware 17 R5's BIOS. Please fix these issues for the next release.

(My distro is Arch Linux. I am running the latest publicly-available BIOS. The fact that these issues occur on Linux does not mean that Windows is safe -- it's likely being affected as well.)

The Alienware 17 R5 BIOS is missing a hotfix that the Linux kernel is expecting it to have. (source)

dell-smbios A80593CE-A997-11DA-B012-B622A1EF5492: WMI SMBIOS userspace interface not supported(0), try upgrading to a newer BIOS

According to the Linux kernel, having WGDS without WRDS is nonsensical, because WGDS requires WRDS. (source)

iwlwifi 0000:47:00.0: BIOS contains WGDS but no WRDS

From what I read online, these need to be set in order for voltages to work properly. (source)

platform regulatory.0: Direct firmware load for regulatory.db failed with error -2

I would think that this could lead to broken or duplicated buttons.

iTCO_wdt: can't request region for resource [mem 0x00c5fffc-0x00c5ffff]

Apparently means the touchpad firmware can't be updated?

From what I read online, these are unimportant messages from the Linux kernel, and there is already a motion to remove them. As such, these may not be particularly relevant to DELL; but I'm mentioning them, anyway. (source)
