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.

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 :
