You've missed a crucial part - this bug was fixed, and then fixed again,
and it went like this at least four times.
Which means that all previous fixes were incomplete.

You mean, here, at debian-user? Someone might be able to provide you
with yet another workaround, which may or may not solve this problem for

Or, filling a bug at bugs.debian.org? Never hurts, but due to the
obscurity of the problem chances of solving it this way are slim.

Or, you meant bugzilla.kernel.org? See above.

Yup. But HDDs do. SSDs are considered obsolete (NVMe is a new shiny toy).
Conventional SASes are going into happy land faster than you can blink.

We're living at interesting times - RAM amount is more or less static,
but I/O capacity grows with each passing year.
