Unfortunately, I'm running out of ideas for now. It seems that the problem isn't caused by a logic error within the driver then but rather some incorrect handling of the hardware. The public ally available documentation for these chips is heavily sanitized and totally unusable for writing drivers though. The only remaining thing to test I can think of is whether this issue is related to the header splitting, which is enabled by default. To disable, set the loader tunable hw.bce.hdr_split to 0 or to be really sure, change the bce_hdr_split default to FALSE in the driver and recompile it. Marius
