Dear All,
I'm porting the 2.4.0-test4 kernel to my Scout Board
(MPC750/MPC8260) and I have finished everything until
executeing the init process (shell) on the remote
filesystem (mounted over nfs).
When the kernel executes the init process (in my case
a programm which calls only a printf and then sleeps
forever) I get a Machine check exception (the backtrace
tells me in set_brk called from load_elf_binary).
Does anybody know whats going wrong? Whow has my remote
root filesystem look like (I have compiled my own glibc,
modprobe, sh and ls)? Is there any information on the web
available?
My remote filesystem looks like the following:
PCC141:/tftpboot/LinuxPQ2 # ls -lR

Hi,
I met the same problem with 2.4.0-test2 or test9 kernel on the sandpoint
603e/MPC107. The problem happened on executing /sbin/init both on nfsroot or
root fs on IDE. The backtrace and printk messages show that exeception(or
hang-up) is in pad_zero() from load_elf_binary (fs/binfmt_elf.c).
Thanks,
Haitao Zhang

Hi,
I tried to change one line in eepro100.c and now the 2.4.0-test9 boot is ok.
$ diff eepro100.c eepro100.c.orig
1098c1098
< outl(TX_RING_ELEM_DMA(sp, sp->dirty_tx % TX_RING_SIZE),
---
> outl(cpu_to_le32(TX_RING_ELEM_DMA(sp, sp->dirty_tx % TX_RING_SIZE)),
It seems like the endianess is changed twice so the kernel hangs up. Maybe
we should define some macros like outl for CONFIG_SANDPOINT.
Thanks,
Haitao Zhang
