Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.13 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.

Also see bug #1293361.

[Adam Lee (adam8157)]

bug #1293361 is not the same issue.

@Jens,

1, could you please try another normal mass storage usb disk? better with USB3 feature.
2, please try the latest upstream mainline kernel, http://kernel.ubuntu.com/~kernel-ppa/mainline/ as #3 said.

[rbonsai (tr33)]

The problem still exists here with various USB3 disks.
System information: MacBook Air 6,2 with two USB3 ports
Kernel version: 3.12.13-031213-generic

reading large amounts of data seems to be no problem, but when writing data, the error occours:

I have cross-checked the disks on different systems with USB2 ports: its not a faulty disk!

Help and solutions is highly appreciated
