Attached are the copies of kernel output I get on successive tests as I do them, I'll update as I go. In this copy, over the weekend I ran the hardware using EXT3 rather than EXT4 just to be sure it wasn't a filesystem issue and sure enough I was able to produce the error on both.
With a mainline kernel installed I'm starting the test again, expect an update in the next day or two. For reference, this is what I've installed in terms of kernels: ii linux-image-2.6.32-02063221-generic 2.6.32-02063221.201008271307 Linux kernel image for version 2.6.32 on x86 ii linux-image-2.6.32-21-generic 2.6.32-21.32 Linux kernel image for version 2.6.32 on x86 As an aside, I've switched to a D525MW from the D510MO, the apport submission above was done on the 525, the logs attached are from a 525 and from here on out I'll be sticking to the 525. ** Attachment added: "Test Logs" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/672751/+attachment/2300215/+files/error_listing.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/672751 Title: USB Mass Storage I/O Error To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/672751/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
