The USB gadget support build into the latest Angstrom kernel (as of the 6-6-2013 version), had debugging enabled in it's configuration. This causes the following 7 messages to repeat in the logs:
[ 8732.441147] gen_ndis_query_resp: RNDIS_OID_GEN_RCV_NO_BUFFER
[ 8732.444806] gadget: rndis reqa1.01 v0000 i0000 l4096
[ 8732.445090] gadget: rndis req21.00 v0000 i0000 l36
[ 8732.448797] gadget: rndis reqa1.01 v0000 i0000 l4096

[ 8732.453162] gadget: rndis req21.00 v0000 i0000 l36
This "SPAM" makes the log nearly unusable if you are watching for something else important.
The particular configuration item is: CONFIG_USB_GADGET_DEBUG=y
Robert Nelson confirms my suspicion here (eewiki.net) and indicates that the next build will have this configuration changed.
I am not aware of any way to correct this short of rebuilding the kernel. I think I can wait for Robert... :-)
