Disclaimer: I am not asking for help; I am sharing my experiences,
I happened to get the message "General Protection Exception" while OFW
was installing os126. [That is, during 'fs-update u:\os126.zd', when
about one inch of the screen had gotten filled with green squares.]
Did the complete reset (disconnect AC and battery for a minute) -- then
fs-update ran correctly.
Don't know why I've been seeing this situation now, and not earlier. My
XO-1.5 does have a cat. 6 internal SD card - but the system has been
running well with that SD card for about a month now.

p.s. My memory may be unclear, but it seems to me that my system with
os126 is "snappier" than it was with os125.

Hi,

I think your unit may be developing a fault, since you're seeing
General Protection Exceptions fairly frequently and the rest of us
aren't. Wad, would you like us to get it back to 1cc (and send Mikus
another)?
p.s. My memory may be unclear, but it seems to me that my system
with os126 is "snappier" than it was with os125.
I can't think of anything that would explain this, so it's probably
imagined.

Has the weather warmed?
Is it a B2? Perhaps the heat spreader has shifted?
This can be tested in OFW: (I'm not asking you to do it, I'm sharing my
experiences).
ok dev /switches
ok .temp-rise
Testing heat spreader ... temperature rose 6 degrees C - OKAY
ok
On a B2 here, it rises 12 degrees C and is marked FAIL.

This is inside an air-conditioned residence. The room temperature ought
to stay within a range of plus/minus three degrees F.

It's a B2. But I believe the heat spreader is screwed into place.
This can be tested in OFW:
ok dev /switches
ok .temp-rise

On mine it rises 13 degrees C and is marked FAIL.
I could not find the VIA spec sheet with temperature limits - but many
modern chips have a limit of 80 degrees C or higher. The application
with the highest processing requirements that I run is Timidity (it
requires interpolation and massaging of digital audio data -- resulting
in a continuous XO-1.5 processor workload of at least 40% of the cpu).
With Timidity running, 'sensors' tells me the temperature gets to 71 C.
[The XO-1.5 back does not get warmer than some XO-1 backs.]
