Is there a particular reason why you're using a block size of 512M? Have you tried just leaving it at default? Have you tried changing the scheduler for sdb to deadline? echo deadline | tee /sys/block/sdb/queue/scheduler Have you tried changing the scheduler of ALL disk devices to deadline? I'm not 100% sure that this would not happen on pretty much all Linuxes, as USB is pretty slow. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1030516 Title: 152d:2338 High IO when writing to USB devices To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1030516/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1030516] Re: 152d:2338 High IO when writing to USB devices
Alan Pope, thank you for reporting this bug and helping make Ubuntu better. Could you please test the latest upstream kernel? It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please do not test the kernel in the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please remove the 'needs-upstream- testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. As well, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream', and comment as to why specifically you were unable to test it. Please let us know your results. Thanks in advance.
