Hi,
My kernel hangs by initializing the system. My target is Alchemy DB1200. I use crosstool-ng to build MIPS cross toolchain and ptxdist to build ext2 filesystem. kernel version:linux-2.6.22
I added some printk's linux/init/main.c to see what happens.
#############################################################
. . . (void) dup(0); (void) dup(0);
/* * We try each of these until one succeeds. * * The Bourne shell can be used instead of init if we are * trying to recover a really broken machine. */ if (execute_command) run_init_process(execute_command); printk("before /sbin/init\n"); run_init_process("/sbin/init"); printk("before /etc/init\n"); run_init_process("/etc/init"); printk("before /bin/init\n"); run_init_process("/bin/init"); printk("before /bin/sh\n"); run_init_process("/bin/sh");
it hangs after /sbin/init
What could be the problem?
I tried to give init="/sbin/abhi" "abhi" is an executable file with printf statement. but kernel stops after :
