That looks like you may have a problem with the connection to your
target, so gdb can't really talk to the gdb server.

But i am able to setup initial connection, and also first breakpoint gets hit. Is it like gdbserver (for mips) doesnt support single step command? or is it like i have not configured gdb properly ? I have downloaded fresh gdb-6.4 src, and ran "configure" scripts on my target (sibyte). Am i missing anything ?
