Update. I had a friend with a power supply checker check the power supply. The +12 volt line is running at 11.5v, barely within spec. Fishy, but livable for the nonce.
I had been running Finnix as Debian wouldn't boot. I pulled all the external USB lines except for a 3.5" external floppy disk drive. The USB problem that started all this went away, i.e. I stopped getting error messages in dmesg. I rebooted Finnix, and did not see the error message. Also, the boot speed was back to normal. An hour and a half ago I booted to the installed Debian system, and that now runs fine. I see no error messages for USB or for any of the drives. RAID looks nominal. I will monitor. The next step will be to add back external USB lines, one at a time, and see if the problem re-appears. It may have been something as simple as mild corrosion on a connector. Meanwhile, I did long tests on the hard drives and SSD; all passed. I've seen no hard drive error messages all day.

Would that have solved this transposition? I suspect that Linux sets up the boot drive as sda regardless of how the firmware sees things.

Interestingly enough, memtest86 locks up right at the 4096 MB mark. It also completely refuses to run on another system I have here. I'm going to do some further testing, then report what I see in a new thread. > > > If and when you have convinced yourself that all of the hardware is > good, then software is what remains.

I think so; see above. -- Does anybody read signatures any more? https://charlescurley.com https://charlescurley.com/blog/
