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. > Is there any value in continuing to whine about this problem? 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 you. 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. > I mean, it's not like large-capacity RAM is going away. 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. Reco
