Hi. I've been running a 6-current box which I upgraded recently to 7. At the same time, I disabled WITNESS and INVARIANTS in the kernel. I've noticed the machine doing some very weird things ever since. All daemons appear to be listening and responsive, but no data gets submitted back. eg. I connect to port 22, get the ssh banner, and then nothing else. If I ssh into the system and issue a command like uptime, I get a response back, but if I try an interactive session, it fails. No core dumps, and the machine needs to be cold rebooted, at which point it functions happily for a random time period (shortest 8 hours, longest 1 week), and then symptoms re-occur. I have three other machines running this very flavour of 7-current (all cvsupped at the same time from the same cvsup server), and they are behaving. Those are both Intel boards and processors though. I re-enabled WITNESS and INVARIANTS, and see this in the dmesg, which points to some kind of ACPI / AMD interaction issue.
