Good morning.
I recompiled my linux-2.7.17.11 kernel with CONFIG_BDI_SWITCH removed and now can step & next. I can also break on sys_init_module where a module is loaded and its init routine invoked. Can someone confirm the factoid that CONFIG_BDI_SWITCH may have something to do with precluding step & next from a gdb/kgdb connection across a serial port? Also, it looks like the module I am interested in is not compiled with debug info even through CONFIG_DEBUG_INFO is defined and -g is put into CFLAGS in the top level Linux Makefile. I say this because ppc_85xx-objdump -S module.ko does not show source lines. Can some confirm that there is another setting somewhere to compile a module in drivers/... with debugging info so I can step through its module_init routine. Charles
