What could be the reason for this error?

"usrp2: channel 0 not receiving
usrp2::rx_samples() failed"

I'm using the latest git trunk version, I've change the firmware (to 
txrx_raw_eth_20100608.bin) and the fpga image (to u2_rev3-20100603.bin) (I am 
using USRP2 + RFX2400). And the error still occur! Why?

My top_block basically contains a usrp2_sink and a usrp2_source block and a 
rx_path and a tx_path. The rx_path and the tx_path are changed during runtime 
with the following sequence:


The error occurs after a random number of switches of the different paths 
(sometimes it works for 30 switches and sometimes just for 3) and the program 
requires a restart to get rid of the problem.
