I managed to track down the patch.

https://github.com/RobertCNelson/stable-kernel/blob/v3.7.x/patches/omap_sprz319-erratum-2.1/0001-Fix-sprz319-erratum-2.1.patch

I don't know offhand what rev opensuse uses of the kernel.

The deal with the bug is it takes a while for the hub to fail. I've run it as much as a day before it failed. Because the ethernet uses the usb hub, the only way to analyze the problem is via the serial port. But to make it fail, you need to flog the ethernet or usb.

Just a FYI, as a posted some time ago on this list, there is a bug in the Beagleboard XM in the USB hub chip. A patch needs to be used fix the kernel. (I believe I had tried Fedora 17.) I don't have the link handy, but can dig it up later if my email can't be found in the archive. In any event, the Beagleboard XM will lock up without this patch.

I don't remember that, if you could dig it out that would be great.
 
I was able to persuade opensuse to make a patched kernel for me to verify that the patch works. The patch will be in the factory opensuse 12.3 release. I still have the Beagleboard XM handy to test Fedora should someone make a test image for me. (Compiling kernels is a bit beyond my skill set. OK, way beyond my skill set. ;-) ) My Beagleboard XM is worse than most, so I can see if it fails in a day or less.

What kernel version are they shipping in 12.3 factory for the beagle device? I have a XM myself that I've been testing with.
