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 v4.5 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.

The error can be triggered more likely by playing MP4-Videos in Firefox or VLC, but it also happened with the Parole player or idling. I first thought of an hardware issue, but memtest gave me no clue AND it also happened similarly inside a Oracle Virtual Box on another, completely different hardware. The only similarity was using 64-bit SMP (mine is AMD, theirs were Intel). Most of the time the system freezes completely, repeating the last half of a second of the sound that was playing over and over again. I also have seen a few kernel panic screens (which I am hopefully able to attach) with multiple kernel versions. If the error is pointing to the ATi graphic's driver, I also want to add that I am not using any proprietary drivers. Even though kernel panics aren't logged, I try to include everything I can think of. For the logs attached let me hint at the time of the last panic which occured at March 17th between 11:17 and 11:20 CET.
