So I have dig in it, and it seems that in the past:

usrp2/firmware/include/usrp2_eth_packet.h:#define U2_MAX_SAMPLES        370

but at same time:

gr-usrp2/src/usrp2_base.h:#define USRP2_MIN_RX_SAMPLES 371
usrp2/host/apps/tx_samples.cc:#define   MAX_SAMPLES (371)
usrp2/host/apps/test_mimo_tx.cc:#define MAX_SAMPLES (371)

and now on last version:

usrp2/firmware/include/usrp2_eth_packet.h:#define U2_MAX_SAMPLES        371
gr-usrp2/src/usrp2_base.h:#define USRP2_MIN_RX_SAMPLES 371
usrp2/host/apps/test_mimo_tx.cc:#define MAX_SAMPLES (371)
usrp2/host/apps/tx_samples.cc:#define   MAX_SAMPLES (371)

so I guess it was an old bug in the firmware code ?
