I can confirm this. My CC1000-based motes work fine with the 2.0.2 release but crash with the latest cvs. I run a modified BlinkToRadio to test, with one node only transmitting and the other node only receiving. The transmitting node works ok. The receiving node seems to crash. As a test, I turn on an LED in Boot.booted() and don't turn it off in any part of the code. This LED blinks or turns off at various times on the transmitted node, which indicates that the mote is rebooting. ALso, the first packet from the transmitter is always received properly, with the erroneous behavior starting with the second packet.
Thanks for the help.
