I have a limited experience and can only share that the kernel I
currently am running on this Fire T2000

Linux narya 5.9.0-5-sparc64-smp #1 SMP Debian 5.9.15-1 (2020-12-17)
sparc64 GNU/Linux

Is quite stable for me: I did compile with high loads (e.g. compiling
linux kernel on all 32 cores) and sync the git repository of linux
kernel and ArcticFox browser. GIT sync of such repositories in my
experience is a good stress, I had disk drivers crash, network freezeĀ 
on different architectures and systems. But not in this case.
However, i did not try to run for several days compiling, so I don't
know if it is stable for a long time.
