Dell XPS 13 9360 - lots of machine check exception-messages
Is anyone seeing lots of messages like this on a DELL XPS 13 9360?
I get this with any kernel I tried - Ubuntu 16.04.1 stock kernel, latest vanilla as well as mainline (both Ubuntu & Arch linux).
[ 0.041088] mce: CPU supports 8 MCE banks
[ 0.041097] mce: [Hardware Error]: Machine check events logged
[ 179.824402] mce: [Hardware Error]: Machine check events logged
[ 470.709754] mce: [Hardware Error]: Machine check events logged
[ 6943.396310] mce: [Hardware Error]: Machine check events logged
[10054.482683] mce: [Hardware Error]: Machine check events logged
[10166.746861] mce: [Hardware Error]: Machine check events logged
[11087.548612] mce: [Hardware Error]: Machine check events logged
[12090.893965] mce: [Hardware Error]: Machine check events logged
[12718.384254] mce: [Hardware Error]: Machine check events logged
[13489.322288] mce: [Hardware Error]: Machine check events logged
[14100.885807] mce: [Hardware Error]: Machine check events logged
[15566.970294] mce: [Hardware Error]: Machine check events logged
[16261.061946] mce: [Hardware Error]: Machine check events logged
[17441.723740] mce: [Hardware Error]: Machine check events logged
[24777.496754] mce: [Hardware Error]: Machine check events logged
[27846.728994] mce: [Hardware Error]: Machine check events logged
Nothing reallly seems wrong though. It's just this darn message. Anyone else seeing them with dmesg|grep mce?

@Community,
I've been able to replicate the behavior outlined in the original post and therefore submitted the question to Dell engineering. Engineering came back and advised that the Dell related hardware/firmware is working as designed. There should be no negative impact from the observed log entries.

Hi Yury Vidineev,
I'm unfamiliar with that site. Please use the BIOS as shown here.
If you have any trouble updating the BIOS inside of the OS you can put the BIOS file on a USB key and then boot to the F12 menu. There's a BIOS update feature there.

This site allows Linux systems to update BIOS from fwupdate or Gnome Software. You can see additional details in this Dell announce about support:
en.community.dell.com/.../dell-firmware-updating-under-linux
It worked great with previous BIOS update but doesn't work this time. Probably someone from Dell team forgot to load new BIOS version to LVFS

Probably Mario Limonciello from Dell can help with fwupd
via blogs.gnome.org/.../

@Yury Vidineev,
I went back to the page and 1.3.7 shows added at 2017-07-25 03:54:13, after your mention from the 24th.
