Interesting thing is that this only happens if the system has 10 GB RAM. My system has 2x1GB plus 2x4GB DIMMs, and when I remove one of the 4 GB DIMMs (thus reducing the amount of memory to 6 GB) the problem does not appear. To rule out the possibility of bad DIMM I have run memtest86 for several hours without finding any problems, also the system is rock solid with 10 GB RAM when I remove the USB wireless adapter and use wired Ethernet.
So this implies that the host side influences on the problem. Oliver, any clue? Some DMA issue?
It does look like DMA. We need to determine which HC is used. Please provide the output of "lsusb -t" -- You are receiving this mail because: You are on the CC list for the bug.
