Disabling ehci_hcd as per this article appears to get rid of the problem: http://www.thinkwiki.org/wiki/Problem_with_USB_2.0
But this isn't a great workaround as usb transefers become agingly slow. I can reproduce this on one laptop with two different makes of externel usb drive. The same drives work without problem on another laptop. Therefore it does seem to be a peculiarity of the usb controller. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/696212 Title: Soft cpu lock copying files form external usb drive -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
