Installed 3.9., but did not see an improvement, sorry. At least I now have a way of reproducing the bug. I am just streaming a lecture on linear algebra on youtube and downloading an Ubuntu ISO at the same time:

After 10 to 20 minutes the bug hits me. The driver tries to send commands to the queue, which returns an error:

Error sending REPLY_SCAN_CMD: time out after 2000ms.
Current CMD queue read_ptr 94 write_ptr 120

The read_ptr stays at 94 at subsequent tries, while the write_ptr increases until the queue is full, which is when the driver crashes. I found something on this in an archlinux wiki. See link under "Suspension":

Although my bug occurs even if I never suspend. If I feel like I will compile the kernel with those flags. Again: this sucks and I'm not receiving any response.

@Eryn: What did ProSupport say? How did your replacement work out for you? I just realized that your CurrentDMesg.txt doesn't display the same bug as mine, so I might be in the wrong thread anyway. Could you nevertheless tell me whether you can download and stream the two links I posted above for more than 30 minutes? Thanks in advance.
