[SOLVED] Problems with XMG C405 - random Kernel Panics

cat /etc/modprobe.d/nouveau_blacklist.conf
blacklist nouveau

- No proprietary nvidia drivers installed
- nvidia disabled in BIOS when I'm using Linux
- Gnome3 DE

Now, the are a couple of issues that are quite annoying

1) Random Kernel Panic's:
- sometimes even before boot process finishes
- most often happens when some code gets compiled (?) eg:

pip install psycopg2

triggers kernel panic in 1 in 3 tries, and quite often when installing packages from AUR
- I've tried installing latest Ubuntu (15.04 and 15.10) installation process dies with Kernel Panic ALWAYS, straight after "Coping files finished" stage/step, probably when compiling something...

2) Touchpad
- works with no issues 90% of time
- when it dies I have to do full power-off/on cycle, just reboot does not helps.

Any clues how can I debug/pin-point the issue?

Re: [SOLVED] Problems with XMG C405 - random Kernel Panics

Have you got the Intel microcode updates installed?

No, it didn't "fix" anything. It just shifted the brokeness one space to the right. - jasonwryan

I forgot about microcode, I followed wiki page to get this working, and got a Kernel Panic on first reboot second reboot worked so I can post this...

You need microcode revision=0x13 to fix the typical crashes for this processor.  It is in the latest release of the intel microcode data package, so you may need to update.

Whether this will fix your particular issue or not, I do not know.  But I do know one cannot trust that processor with microcode revision 0xd to run stable.  Also, check with your motherboard/system vendor for a BIOS update.

Re: [SOLVED] Problems with XMG C405 - random Kernel Panics

Thanks for pointing me onto this, unfortunately intel-ucode package does not contain microcode update for this CPU (yet)
I followed this BUG report: https://bugzilla.kernel.org/show_bug.cgi?id=103351
and found here updated microcode: https://github.com/bgw/bdw-ucode-update-tool

Testing now, currently looking promising...

[EDIT]
Marking topic as solved, microcode update from bgw repo looks like a fix for my issues.
