Hello,
I have encountered a big bug here with ICH9M hardware.
Switching to a newer kernel, namely 2.6.37-20-desktop (opensuse 11.4 rc1),
does not solve the problem.
The same application ran perfectly with an ICH7 hardware.
I have a serial GPS receiver connected to a USB port.
As long as I do not use it, even if it stays connected, my disk works
fine. But, as soon as I start to listen to this USB serial GPS receiver,
I get errors for every disk access, until I reboot my computer :(
>From the messages below, DMA transfers block (READ DMA as below, and
I have seen WRITE DMA frozen also).
The running running processes keep running, and the GPS listening process
continues to get messages from the USB GPS receiver each second.
Is that a known (an fixed) problem ?
Here is a console log excerpt showing the messages appearing after I start
listening to my GPS USB receiver, recorded using netconsole :
