So, I've been hit with the Ubuntu bug that causes hard-locks on heavy network usage, or possibly file writes. Basically, any time I download heavy amounts of traffic from the web (usually usenet or torrents), my system will hard-lock and my only option is to hard boot. There are no errors listed in any of the log files. It seems like it may be related to the filesystem as well, since actions like par2 or unraring often initiate the crash.
My system's basically unusable at this point. I'm considering upgrading the repositories to the Ubuntu 9.10 alpha release. My only other option appears to be a fresh install, which doesn't appeal to me. Has anyone had luck doing this? Is there a Mint-specific alpha release alongside the Ubuntu releases?
