I've now tested with a clean/vanilla kernel 6.6.2 with all the patches from https://git.kernel.org/pub/scm/linux/kernel/git/stable/stable-queue.git/tree/queue-6.6?id=2da2670346795f8fe06acbf499606941303b9cbe applied on top, but *excluding* the "af_unix: fix use-after-free in unix_stream_read_actor()" patch, and my VM boots cleanly, without any crashes. When I try to boot a build of the exact same kernel, but *including* the "af_unix: fix use-after-free in unix_stream_read_actor()" patch, the VM crashes during boot (as stated in my previous email), so I'm now 100% certain that this patch is causing the crashes.
Can you try booting the latest 6.7-rc and see what happens? That might give us a further clue. I'm running 6.6.3-rc with this patch, various apps use Unix sockets and there is not problem so far. -h
