General Protection fault (GPF) Ultra 2 hangs unresponsive

i'll tell ya what's even weirder for me -- i have made NO changes. no upgrades, no downgrades - still on same firmware - and as quickly as the GPF's started happening, they've now stopped. been 3+ weeks for me, as well, without a crash. very strange to have come on with seemingly no cause, and then go away with seemingly no resolution. i find this spooky odd.
