I've installed it using go install method, qemu version 9.2.0.

I was able to overcome this issue be applying the following patch, which also required me to increase timeouts in certain cases:

diff --git a/vm/cfg.go b/vm/cfg.go

Thanks for bringing this up and for documenting the workaround, though please note that I am able to do much since it is a bug in QEMU, not in Linsk.
