(In passing, I'd love to > learn how you generated it so that I can try my luck with #987377.) Quick steps: - I created a Debian bullseye install with a kernel version matching the installer, and also installed linux-perf(-5.10) - From the running, already stuck installer, I mounted the existing install, did the whole mount --bind stuff for sys, proc, dev. I cannot remember if one needs to actually chroot. - And then its mostly `perf top` and/or `perf record` + `perf report`. The former gives you an immediate view, while the latter writes into a file which you can look at later. Having more debug symbols would have been useful, but I did not manage to set that up. Chris
