Re: JFFS2 directory copy problem

[Cmmn Ml <cm...@ya...>]

Hi all,

I'm using linux kernel 2.6.21-rc7 with the sh: Solution Engine SH7705 board and CPU updates (http://git.kernel.org/?p=linux/kernel/git/lethal/sh-2.6.git;a=commit;h=5452d25e28f365938b36f3a972fe2a1bb69a4c3e) added by Nobuhiro Iwamatsu to the sh-2.6.git.

Initial boot up of the kernel works fine, I'm getting the early console outputs, printk is working, but after the ram disk is mounted and when the init/main.c starts the /sbin/init, I'm not getting the system console. This ram disk with the busybox ver 1.00 was working fine with 2.6.16.9 kernel (with sh--stable--2.6.16 patch). 

To find out the problem, I replaced the /sbin/init with a small helloworld program (dynamically linked) which has only a printf in a loop, then I noticed that the printf is not working. This program was also working fine with 2.6.16.9 kernel (with sh--stable--2.6.16 patch).

As a summary, my situation is the system boots up fine, printk is working fine but printf is not working and also busybox is not able start a console. This might appear like a crazy question, but if any one have some idea about this, it will be a great help. Following is the early console output of my system.

This doesn't exist in sh-2.6.git, or even 2.6.21. Please use a current
kernel before submitting bug reports that have no relevance.
