<br></blockquote></div><br>Wanted to get back to this in case someone else ran across this in the future and this can help them.<br><br>Investigation
continues but there's something SERIOUSLY wrong with the old PC I had
my backend in. I can't track down what it is, but I don't think it was
drive.<br><br>Both bad blocks and SMART tests (short and long)
came back with no issues on the drive at all, given this thing is only
about 6 - 7 months old, I'm inclined to believe that there's nothing
wrong with the drive...to the point I did a new build/restore to it.<br><br>To touch on a few items:<br><br>*
Cabling: Unlikely, no frays and nothing has been inside this thing
since I set it up a couple years ago. I did check all the connections
and they were solid. I guess there's a possibility of a wire burning
out, but I have my doubts, these cables look in pretty good condition.<br>*
Power Supply: There's a potential culpret, the PS is probably 3+ years
old at this point (maybe more). Usually when I lose a PS I end up
losing the system (simply "turns off" and won't turn on and/or the whole
thing doesn't boot properly). There is the possibility that it's just
on an edge where there's only BARELY enough power making it out of the
PS to keep the system alive. It would explain a few things (see below).<br>*
Heat: VERY unlikely an issue. All fans are active and working
properly and this case is a top of the line Antec from a few years ago.
I ran my main gaming desktop out of this case for the better part of 4
years...if THAT wasn't going to overheat, this unlikely would.<br>*
Bad Memory: Here again is a possibility. I didn't get a chance to run
memtest on it, I may go back and do so just to see what I can figure
out.<br><br>Reinstall:<br>----------------------<br>So I
went ahead and started the process of re-installation. After
determining the HD didn't look like it was at fault, I decided to just
use the old hardware and see what I could do with it.<br><br>That's
when I ran into the installation errors. LOTS of installation errors,
across pretty much every version and implementation of Mythbuntu I could
try. <br><br>* USB Key Install: Mythbuntu 14.04 - I must have
tried this 10 times in different iterations. It'd get through the
download/copy of packages and (I think) start the actual install of them
(something about building a list of packages on the CD? Whatever the
step is in the install after the "copying packages" part) and the
installer would core dump/seg fault on me, every time.<br><br>* CD
Install: Mythbuntu 14.04 - Same issue as above. Also got several
reports from one of the subsystems during the install that it was
failing / dumping all throughout the process before the installer
finally crashed on me.<br><br>* USB Key Install: Mythbuntu 12.04 -
Decided to go back to 12.04 and see if I could make IT install
properly..maybe my hardware is too old for 14.04 to work well?
*BUZZZZT* nope, that didn't work either. Same core dumps/seg faults in
the installation.<br><br>I skipped trying to CD install of 12.04 as by this point I was pretty convinced something was wrong.<br><br>Moved
everything over to a secondary Linux system (Del Optiplex 740) I
"inherited" from someone a while back and installation went through
flawlessly...first time, no issues. <br><br>As if that wasn't
enough to point a finger at some other piece of hardware on the box, I
ended up dropping the Dell's drives (I swapped the Myth backend drives
for the Dell drives and visa versa, in essence switching systems) back
into the failed Mythbackend's box and booting it. System came up, but
is only stable for about an hour or two till I get some kind of kernel
panic with it literally just sitting there. If I happen to go into X
(actually log in), it happens in about 5 10 minutes of use.<br><br>Kernel panic seems to indicate some kind of issue with CPU, I also thought I saw some kind of error with graphics card. <br><br>Given all this, I'm inclined to believe one of a couple things:<br><br>*
Power Supply: My Primary suspicion is, given the age of the box,
there's a potential that the PS is just not supplying enough power to
the system anymore...causing all the misfires.<br>* Motherboard:
My secondary suspicion is that the Motherboard has given up the ghost.
Given the kernel panics and seg faults I was getting during installation
on this box, I wonder if there's not just something broken with the MB itself...could account for the CPU and Video Card Errors.<br><br></div><div class="gmail_extra">I suppose it COULD be the CPU that's broken, but I've never seen a CPU give out (It's got a hella good aftermarket cooler on it). I don't think the video card is to blame (I can't see where the video card would be the culpret in all the issues) but maybe I'm not looking at something right.<br></div><div class="gmail_extra"><br></div><div class="gmail_extra">Anyway it goes, the old Myth box is pretty much ADR (Ain't Doin' Right) and at the moment, I just don't have a whole lot of need to take that diagnosis any farther than I already have.<br><br></div><div class="gmail_extra">--Doug<br></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div>
