Oh, you can run a 5.16.y kernel on Alpha?  I have had problems
with everything since 5.9.y with rare, random, corruptions in
memory in user space (exhibiting as glibc detected memory
corruptions or segfaults).

This is why I am still running a 5.8.y kernel on the Debian
Ports buildd.

I just compiled up a 5.16.y kernel and the problem is still there.
It did take a bit to trigger the bug (about 10 hours of testing
before it happened).

I had done a bisection between 5.8.0 and 5.9.0 last year but I
think it went astray (as testing is difficult and not fool proof).
You email has prompted me to go back to it and see if I can nail
down the offending commit.  We really want to get it fixed.

Cheers,
Michael.
