The result of the bisection is
[88dbcbb3a4847f5e6dfeae952d3105497700c128] blkdev: avoid migration stalls for blkdev pages
Is that result relevant for the problem or should I continue bisecting between 4.20.0 and the so far first bad commit?
Can you try reverting the commit and see if it makes the problem go away?
Tried reverting it on top of 5.0.0-rc6-00153-g5ded5871030e and it seems to make the kernel work - emerge --sync succeeded.
Unfinished further bisection has also not yielded any other bad revisions so far.
