Dear All, I have a problem with load_elf_binary() stalling my linux 2.4.0-test9 kernel. Through the use of printk's I have traced program flow all the way up to a call to clear_user( (void *) elf_bss, nbyte ), called from binfmt_elf.c padzero(). A printk immediately after this fucntion call never gets printed out to the serial console. I said stall above because although the machine appears to "hang", it will still print out to the serial console on receiving a character over the serial port - I have a printk( "+" ) in the serial interrupt. I looked into clear_user() and see that it makes a call to " __bzero ". From a preliminary search on the web I think __bzero is a library function and so not defined in the kernel ( tried searching kernel sources too ). If __bzero is a library function, my first thoughts would be to suspect it and the library that contains it. But I have successfully compiled and ran a 2.4.0-test9 kernel for ANOTHER mips development board using the same compiler libraries etc. The variable in this case seems to be my port not the supporting tools. What I would like to know are : a, are there any docs explaining __bzero, or could someone explain what it does. b, does anyone have any idea why clear_user would hang like this ? eg not set up memory correctly etc etc c, any tips for looking into the problem and tracking down the cause TIA Wayne __________________________________________________ Do You Yahoo!?
