BTW, could you reproduce it on viro/vfs.git #work.dcache-busy-wait? It's possible
that changes in there might accidentally fix that, and if they did it would narrow

Ok, will try.
Please note that building kernel/ installing / running dpkg build takes hours & days,
so it may take quite some time until I come back here....

Which kernel(s) had that been reproduced on, BTW?

This happened with all Debian kernels from (at least, maybe earlier) 6.16 up to 6.19.
Incidentally, can that be reproduced on any of qemu-based setups? And do you need
to build the kernel natively? Debian kernels can be cross-built, after all...
I know, and I do in some cases.
Nevertheless, everthing takes often longer than expected... :-(
