I believe it's a bug in the new version of avarice when dealing with
"sleeping" motes. The easy workaround is to comment out the
asm volatile("sleep")
instruction in __nesc_atomic_sleep() in tos/platform/avrmote/avrhardware.h.
Remember to uncomment this out before building a "real" version, at
least if you care about power usage/battery lifetime :-)
