Aha - it turns out the second workaround (inserting an SD card) stopped working when I re-inserted the little inert plastic insert that fills in the SD card hole when you're not using it.
So the real workaround is to pull that out and leave it out, or to remove the kernel module. This also suggests what is going on - for some reason the driver now seems to be constantly trying to figure out what is going on with the inert plastic insert. I'm guessing that some change for the 3.1 kernel is now kicking off that behavior. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/925760 Title: Constant warnings from the kernel: Test WP failed, assume Write Enabled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/925760/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
