The current Debian user-mode-linux package in unstable is based on

After updating the tree to 5.10.5 and applying all Debian patches
from the package, I cannot reproduce the bug.
I am running it on 5.10, 5.2 and 4.19 hosts with the same parameters
without issues. Hosts are all up to date Debian 10.8 and so is the
UML userspace.
Did you mean 5.10, 5.2 and 4.19 (UML) guests ?
No. Hosts.
I have several 6core/12thread Ryzens which are used for development
testing.
They all use identical userspace with the sole difference being the
kernel. They all use a selection of 5.x because 4.19 does not support
the hardware properly.
The 4.19 testing is done on my old "test farm" which is all A8s and
Athlon X760.
We've seen this happen on Debian Testing and Unstable Host (of which
the former would soon be the next stable i.e. Debian Bullseye).
In our tests, when running the same linux uml binary (5.10) on a Debian
Stable Host, it is working fine.
OK. I will upgrade one of my systems to Debian testing to try to
reproduce this.
