| UEFI BIOS are known to have a myriad of possible bugs, especially older
| ones, like from 2013. BIOS updates are known to have risks. Motherboard
| makers historically have recommended to skip them unless yours is known
| to have particular problem solved by a newer BIOS. As when UEFI booting,
| booting is under the control of the UEFI firmware, and the content of
| NVRAM, corruption of it upon upgrade poses a high risk of things like
| what happened to you. Are your Trixie and Sid installed in UEFI mode? If
| yes, show us output from efibootmgr -v. You may need to purge some junk
| from NVRAM and/or add a new Trixie or Sid NVRAM entry using efibootmgr
| to re-institute predicable boot behavior.

In that I don't have ubuntu on the machine anymore, and haven't for awhile,
I'm a little bit surprised that it's there. I do not know which of the
other three I should keep. Ever since the big BIOS rejiggering of a decade
ago, what once was clear has been a mystery to me. So in addition to not
knowing which one(s) to keep, I have no idea how to get rid of any I don't
want or need. Suggestions, advice, or knowledge from the above?
| Check your installations for automatic upgrades to installation and/or
| firmware. One of these could be the reason why the reboot explosion. I
| disable and or purge such things from my installations. They're mine. I
| decide if and when it's time for things like upgrades or new kernel
| additions to occur on mine.
I do not have anything set to automatically upgrade, for exactly the reason
you state. And I should note that the problem appeared before the BIOS
upgrade -- which from the date brought me clear to 2014 -- which does seem
to have been successful.
