This is a weird bug, has anyone else seen or fixed it?
If you connect storage up to a pandaboard USB port (flash or sata),
you get about 5 MB/sec throughput. Now, if you "ping -i 0.001" the
pandaboard from another host, you can increase the *storage*
performance to 22 MB/sec (for my disk, max 32 MB/sec on an x86
desktop). Note that the ethernet device is itself also on the same
USB hub (on chip) as the device storage.
I recently ran some bonnie++ benchmarks against both an SD card and a
USB 2.0 hard drive and I was seeing about 10 MB/sec on the USB drive.
This was with the 2.6.35-g6d019da-dirty kernel.
I'll have to try this again with the pings and see if that improves the
