USB 3 unreliable

[a_user]

None of my external hdd's or sdcard reader are working on my usb3 ports under ubutnu linux 14.10 (also not on ubuntu 13.10 and stoped working either after an early update during 13.10 or 13.04, can't remember).

lately i decided to report the bug and here is the syslog snippet while i tried writing to an external hdd with ntfs. it disconnected and reconnected.
http://pastebin.com/qXHX6pHN

on another hdd with ext3 formated it just caused io errors. i do not have the logs anymore and may post them if i get the device back again. similar issues with my external sd-card reader.

all of these devices work fine on usb 3 under windows and worked also fine some time in the past under ubuntu.

i try to update this when i can repeat the issue (currently none of this devices are available for me ut will be in the near future).

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.17 kernel[0].

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'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

i will test the latest upstream kernel (already using it except for these tests).

but here the syslog while i was trying to delete files from another external hdd with ext4:
http://pastebin.com/uTue0FZr

and then i tried formating the very same one to ext4:
http://pastebin.com/UQs4x2du

both were done using the current default kernel 3.16.20. The device is working fine under windows connected to usb3, but i think the external hdd has only usb2.

The device used in the log of the opening post was an usb 3 external hdd.

i will try to reproduce this with the latest upstream kernel later.

Tried upstream kernel 3.17.0 from the ubuntu mainline ppa.

No issues with that one. I could reformate my external deive to ext4 and am currently a lot of stuff to it now without any problems.

[penalvch (penalvch)]

a_user, the next step is to fully reverse commit bisect the kernel in order to identify the fix commit. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F ?

[a_user (a-user-sci)]

i'll try when i aget back the device. Had to give it away for the moment.
