Except if it's anything like the Intel ME exploit, physical access can
be faked using a compromized USB device.

You mean the skylake debug port?

No we don't.

Yes we do.
TALOS 2? g505s laptop? kgpe-d16? novena?

I play new games at max settings on a pre-PSP AMD system KGPE-D16 where 
I have installed a libre firmware for the board and the BMC via the 
recent OpenBMC port (the facebook version of OpenBMCless features 
than the IBM version but still quite nice)


The TALOS 2 costs less than a brand new xeon system with similar 
performance and it has better features such as IBM's OpenBMC, PCI-e 4.0, 
SMT4 etc.
The stars have aligned and given us a libre firmware server/workstation 
that is brand new and very very fast.

Re: [gentoo-user] Nvidia-drivers,

Some time around when Spectre/Meltdown were announced, I started
experiencing similar problems.  I don't know "what's wrong" because so
far I have found no answers.

The best I can offer at this point is that on my system, it seems that
it will work with Nouveau drivers much better than the system currently
works with NVIDIA drivers.

Unfortunately, I haven't managed to get a working version of that yet,
but I usually only manage to put a few hours a week on trying to figure
it out.

I fortunately haven't had the problem that I have to kill power to the
computer, though I think I have gone through some times I have needed to
reboot, rather than just get back into X either through killing
processes, or (very rarely) stopping one problematic process which is
the source.

[gentoo-user] Nvidia-drivers,

Gentlemen, we have a problem...

Okay, ~ a week ago there was a power outage at my place, everything goes
down for a day or two. I had recently refreshed my UPS batteries, so I
had a chance to put that into the circuit, no biggy.

Since nobody will offer me a job, I was playing Kerbal space program yet
again. (not even Don Corleone could get me a job at this point, I
frequently joke about the horse head trick but, seriously, I don't think
even that would work...)

So, after all of two and a half days of uptime, nvidia drivers takes
x'-doze down.

I was like "Ok, fine, I'll do a maintenance cycle on my machine and all
will be good..."

So I update the bios, update the kernel, update portage, flush a few
dead packages down the memory hole... Ok, my system was in shape again...

So, I'm back in kerbal, another day or two goes by, I'm sitting there
trying to figure out whether I have enough room in my departure corridor
to slot in a contract mission to Jool.. I wasn't even sitting down, just
poking around in my kitchen. When I got back, the game was frozen. I had
to log in with my PoS laptop which is useful only for this task. I found
that KSP, and X'doze were live-locked, presumably on a Nvidia-drivers
bug. =( I tried killing off KSP but it ended up going zombie... I tried
killing off parent processes, no luck, I then tried shutting down the
machine the normal way, no good. I eventually ended up going to the
dusty 28 year old power commander thing and throwing the big orange
switch labelled COMPUTER (complete and instantaneous removal of power).

What's going on here? Nvidia drivers have been stable for years...
what's the deal? =\
