Okay, so, after having changed the GRUB configuration, this time around, it lasted 1 day, 4 hours, and about 45 minutes before finally blackscreening. Also, during that time, at around 1 day and a little bit over 2 hours in, there was a +wall message across all my terminals saying there was a "soft lockup". Maybe this log has some useful info.
