today I got this dma-debug warning with the ixgbe driver with a kernel
near 2.6.30-rc8.

Hi Joerg, thanks for the report, I thought we had fixed all of these 
already but we must have missed this one.

ixgbe 0000:02:00.0: DMA-API: device driver frees DMA memory with
different size [device address=0x0000000000045c12] [map size=258
bytes] [unmap size=256 bytes]

The following patch should fix it, compile tested only, but it is pretty 
straight forward.

Thanks for the quick answer :) But I tested the patch and the warning is
still there.
