The issue is
fixed in 5.10 upstream stable kernel branch.
And it is currently pending for the next bullseye upload against #1031753:
linux-image-5.10.0-21-s390x: user space process hangs on s390
We found an issue in Debian kernel 5.10.0-21-s390x which causes similar problems and we are working on the fix.
Meanwhile I would request to downgrade all 5.10.0-21-s390x running machines to 5.10.0-20.
I will update this bug once the next kernel version with fix is available to upgrade.
Thanks,
-Dipak
