USB3 doesn't work properly in Ubuntu

[Tommy_CZ]

After pure installation of Ubuntu 14.04.1 none of my USB3 ports works.
I tried to connect few devices, no response in Unity nor KDE, but lsusb can see them:

This is not a bug with the release upgrade process, rather with the system after the upgrade. Subsequently, I am removing the package assignment.

[Tommy_CZ (t-kijas)]

Well, I typed ubuntu and choosed "External or internal storage devices(e.g. USB sticks)".
To what package I should report a bug then?

[Paul White (paulw2u)]

Tommy_CZ, according to https://wiki.ubuntu.com/Bugs/FindRightPackage#Hardware_Malfunctions this problem should have been reported against the kernel.

Are you still experiencing problems? And if so, have you applied the latest kernel updates?

[Joseph Salisbury (jsalisbury)]

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.7 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'.

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

Thanks in advance.

[Expired for linux (Ubuntu) because there has been no activity for 60 days.]

[Tommy_CZ (t-kijas)]

Hi, newer kernel did not help, it seems it is known bug of AMD970 chipset.
GRUB_CMDLINE_LINUX="iommu=soft" is a known workaround.

[Tommy_CZ (t-kijas)]

Same bug with newest kernels...
