Hi Matthew,
I was experimenting with kdump yesterday. It worked "out of the box" on
another computer of mine but not on the one with the freeze-on-resume
problem. However, I got several package upgrades yesterday, including a
new kernel 5.15.0-87-generic. I tried it and I was very surprised to
Hi Zoltan,
The bisect route would be standard debian packages. You would just wget
the packages, dpkg -i them, reboot into it, suspend, resume, remove
