Sorry, I'm using the 2.4.10 kernel and GDB 5.2. What I see happening
is the BREAK 5 instruction from a software breakpoint is hit, and the
kernel loops continuously on that, as it appears to have no way to
deal with that exception. I'm running gdbserver on the MIPS target and
gdb as a cross-debugger on an x86 host (RedHat 7.1). To me, it looks
like when the debugging breakpoint is hit, gdbserver should get
scheduled to run and handle the breakpoint, but instead the child
keep's getting scheduled.
