I have installed 7-RELEASE/amd64 on it. 2GB of RAM, 6GB of swap. The install went fine, but post-install I'm running into a problem where the USB keyboard will just lock up. I can still ping and SSH into the system, but after about 2 minutes of activity, the keyboard becomes nonresponsive. I can move the USB plug to a different port, and see that it's recognize, and the keyboard comes back, but a couple of minutes later, it locks again. I've checked with things in the BIOS, but can't find any setting that makes a difference. I've tried both the 4BSD and ULE scheduler, no changes. Any thoughts or known issues that would explain this? When the lockup happens, there's nothing in /var/log/messages or dmesg to indicate a problem. The only other clues are that sometimes, right before it locks, it will go into a repeat loop on a keypress, and it seems to be able to be reliably triggered by switching virtual consoles (though not exclusively). I've tried different keyboards, so it doesn't appear to be a hardware issue. Thoughts? --Wade
