probably a kernel problem. As you seem to be on gentoo, would you feel
comfortable to figure out what kernel version regressed it? You could
use `git bisect` for that and it might take a while, but that's the
best approach to help out fixing that bug. Do you still know what was
the last good kernel? Maybe I can check the git log and see if
anything stands out or to try out.
