I am experiencing this lock up too in Feisty. I agree with Dan Lenski that it happens when sending data. An easy way to reproduce is to ssh to the machine containing the card and then cat /var/log/messages.
I am willing to ship my card to a developer that is willing to fix this bug. -- r818x driver freezes randomly https://bugs.launchpad.net/bugs/31857 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
