hello  :
    
I'm porting xenomai to SAMSUMG s3c2410 processor (on SMDK2410) as per
porting guidelines. In the first phase, applied
adeos-ipipe-2.6.26-arm-1.12-00 patch found in xenomai-2.4.8 to kernel
2.6.26.8 and have implemented required machine specific code.  add a driver of CS8900, 
kernel booted but with a problem , kernel doesn't boot VFS and ipconfig. 

what hanpen that  I  doesn't  konwn ;

Following are last few kernel boot log messages:

That was unneccessary. This ARM processor is supported for more than 2 
years.

It looks like you have reinvented the wheel:
- the linux kernel already has a driver for the cs89x0 ethernet interface;
- Xenomai already has support for the s3c chips.

Well, your I-pipe support is probably buggy. Did you check whether the
hardware timer is still ticking when the kernel stops? I am afraid if
you want to write your own I-pipe support you will have to debug it...
