Hi,
I've been running FreeBSD 10.3 on a Dell Optiplex 755 with a Radeon 2400XT card. Performance is great (really great) on such old hardware, but I see an occasional error in the system logs (happens about once in 2 months or so). The machine is only rebooted for updates.

When this happens, sometimes the screen will briefly flicker, but often it's completely unnoticeable. I've only had X hang once after this error in more than a year. I thought I'd seek some expert advice.
