Here's a plausible theory (and repudiation of the current thinking)  ...  :)

Cool, hopefully they're getting closer to the bottom now.

Here's an odd one for ya. Probably just a coinkydink, but who knows ...

I had a hell of a time getting my 32bit circa 2004 Peppermint/Ubu test machine booted. I hadn't started it in a couple of weeks.

Figured out, my CMOS was scrambled - wouldn't boot - couldn't save changes to BIOS, blah, blah, blah. Sound familiar?  :-\

After a couple of hours or trial and error, I finally got to the login screen. First thing I did was:

Upgraded the following packages:
linux-generic-hwe-16.04-edge (4.13.0.19.26) to 4.13.0.22.28
linux-headers-generic-hwe-16.04-edge (4.13.0.19.26) to 4.13.0.22.28
linux-image-generic-hwe-16.04-edge (4.13.0.19.26) to 4.13.0.22.28

That worked a treat, so I subsequently decided to play it say (judging by the mail lists) and install the Linux 4.14.10 mainline kernel.

Yeah running hwe-edge 4.13 kernel at the moment probably isn't wise.

Theoretically, the issue was fixed in Kernel Version 4.13.0-21

Of course, I had 4.13.0.19 sitting there, like a ticking time bomb ... 

Maybe I should file a bug for all the DFI LanParty PRO875B rev B1  (2004) users out there. LoL!  :D

Yeah! That's cool...
Looked in Synaptic today, but 4.14 is not available. Guess if one needs it, it would have to be compiled from source [emoji848]

I'm assuming you could manually download/install it precompiled from the Ubuntu Mainline Kernel PPA
http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.14.9/

Hi pin,

Yes, what PCNetSpec suggested works fine -- at least on the machines on which I have tried this.

Hi All

but before doing so I assume you have to unload current proprietary drivers - reboot to nouveau - load the new kernel - reboot and then re-install proprietary drivers assuming all is working well...

Yes Zeb that would be advisable.

That said, there no need to do this in Peppermint unless you've switched to the hwe-edge kernel track or have manually installed the 4.13 kernel some other way .. our default kernel is not affected.
