6.1.12-1 and 6.1.15-1 are good. 6.1.20-1 is the first broken one. > A `git bisect` would be best, but grabbing these intermediate versions > (from snapshot.debian.org) is the quickest way to narrow the range. Last time I tried to build Debian linux kernels, it was spending a large amount of time building packages I don't need, and finding the right incantation to reduce that load was not straightforward, and I can't find my notes, unfortunately. If you have instructions I can use to go through a bisect in a quick manner, I'm all ears. Mike
