I'm seeing random panics (unfortunately under X11, and I haven't had the time to build a kernel with DDB_UNATTENDED yet) with a kernel from 2006/01/26 01:30:00 UTC, but not as serious as the ones after the pts changes. What is funny is that reverting the pts changes to sys/kern only from HEAD doesn't solve the syscons problems on FreeBSD/amd64 I've hit, so it is possible that the bug that has prevented HEAD from being usable here for a few days exists in pre-pts code. I'm now rolling back to 2006/01/25 00:00:00 UTC, which seems to be the last date I could build a kernel & userland that was safe to use on my laptop. Then I'll start trying to narrow this down in the commits between: 2006/01/25 00:00:00 UTC 2006/01/26 01:30:00 UTC But it may take a while, since I only have a single amd64 machine here and it builds world+kernel in around 1.5 hours. - Giorgos
