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. -- ------------------------------------------------- Justin Wojdacki justin.wojdacki@analog.com (408) 350-5032 Communications Processors Group -- Analog Devices
