Hi,
first I have the DM816x Eval Board (with Extension Board) and the DM814x Eval Board - and I have self made board(s) running mostly fine with the DM8148.
On my Board I added an TI TUSB7340 SuperSpeed USB (aka USB 3.0) controller and this device seems to run good at the first moment, as it will be found on the PCIe bus and a new USB Bus is added. Even when connecting a mouse or similar all seems to be fine.
Here some piece of the system messages:
PCI: enabling device 0000:01:00.0 (0140 -> 0142)

usb usb3: SerialNumber: 0000:01:00.0
hub 3-0:1.0: USB hub found
hub 3-0:1.0: 4 ports detected
If I connect an USB 3.0 USB Stick, it will be mounted properly and I can read the files without any problem .But if I make a simple mkdir test (no error) and then a sync - the system blocks and after a short period linux comes up with the message that the xHCI controller is died. ***.
Here is the log:

First I thought it correlates with the MSI issue (with MSI/MSI-X enable in the kernel xHCI would run) but after disabling msix in the xhci driver (only allowing msi) - msi will run, but with the same error. Next step was backporting the xhci stuff from the current kernel 3.4.5 into "our" 2.6.37 - even here comes the same error.
Then I use my 816x eval board which as a "normal" PCIe slot, populated it with the TUS7320 Eval Board (the 2 port version of the 4 port 7340) - just to be shure there is no issue with my hardware - and yes there is the same error.
_BUT_ if I exchange the TUSB7320 PCIe card with an "noname" NEC 7202 model this error vanished.
Here the log:

Any hint what I could do ? I want to keep the TUSB7340 ...
