It's just a video freeze-up I think, connecting by ssh to shut it down or reboot still works. I've become a fan or Termux on phones for that reason. Just pull out a phone and use it to reboot your PBP, mostly more convenient than walking to another computer. It's crashing the video at a level lower than X, that's why you can't switch to another virtual teminal.
In my case Panfrost wasn't causing the crashes, they were because the original eMMC was starting to fail so something would try to read or write on a bad spot. My workaround was to set up the Daniel Thompson installation on a new sd card and use it to boot from. I get uptimes of a week or so, it's quite stable. My original eMMC is still in place as a backup boot medium. I have an nvme drive in here but not booting yet, so I periodically boot from the eMMC then use dd to backup my sd card to an image on the nvme.
Actually that doesn't make a lot of sense, a crash due to the eMMC might leave it without ssh and totally dead. But it hasn't happened in months, I was trying to remember exactly. But it was the eMMC because that's the only thing I changed.
I suppose you could find a Panfrost forum or mailing list and ask there about the messages. I expected them to be cured by the apt-get update/upgrade cycle but it's been over a year now. This Panfrost is considerably slower than the video in the mrfixit Stretch. And there's a bug with having your speakers stay on after you plug in headphones that wasn't in the mrfixit image.
Look at the grep man page, it's possible to set it to filter out lines containing a phrase to clean up your dmesg, then pipe it to something else.
