Works fine here with 5.9.2

What is the host you are running at (arch, linux distribution version, container or not?)

fedora 32
amd64 CPU
kvm

I see that fedora 32 was released with kernel 5.6 initially, but you are using 5.11.
Was it some official update? Did you update kernel headers as well and rebuilt nginx?
Was it built on the same machine as you are trying to run?

It is an official update. and I update the kernel headers as well, but does not exactly match.
run on the machine which built nginx.

Should I built linux kernel myself?

ok, I was able to reproduce the issue. It happens only with '-t' flag. This need to be fixed.
