Ok, let's try to disable the syncflood before the test. As root:
# V=$(setpci -s 18.3 0x44.l)
# echo $V
# V=$(printf "0x%x" $((0x$V & ~(1 << 21))))
# setpci -s 18.3 0x44.l=$V
# echo $V
I've added the echo $V so that you can paste them as a reply so that I
can see their values.
And then run the triggering sequence again, better not on an X terminal
but in the text console to see any MCEs when it freezes. I remember you
saying that you don't have serial connected to it so catching the MCE
would need more staring :)
Thx.
