Several of my USB connections (network, harddisks) were instable. This was mainly at ports sharing IRQs, so I thought that might be a case.
Another bug is a more probable cause: I now sudo kill -s SIGSTOP `pidof udisks-daemon` and I haven't seen the instability anymore. ** Changed in: linux (Ubuntu) Status: Incomplete => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/793972 Title: interrupt IRQ shared while plenty free To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/793972/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
