ZFx86 support broken?

ZFx86 support broken?

[Andre]

I am trying to boot LFS6.0.1 livecd which has 2.6.8.1, but the kernel hangs
at:
Freeing unused kernel memory: 456k freed

My system is a pc/104 board based on ZFx86 with 64M ram
I also found this posting:
http://linux.derkeiler.com/Mailing-Lists/Kernel/2004-03/5939.html
Looking at the console output, the cpu gets recognized as 486, whereas
2.4.22 detects the cpu as Cyrix Cx486DX4

Looking at the kernel source, it seems to get stuck after the call to
free_initmem and when I tried to specify init=/bin/sh it still got stuck at
the same place so I figured it doesn't even get to the run_init_process
calls in ..../init/main.c. Could the call to unlock_kernel get stuck?

It looks like it may be having trouble with userspace, try confirming that 
it is indeed mounting root and doing run_init_process.

How can I confirm this? I am booting off a livecd and I have tried to see
whether the 'debug' bootprompt option would give more info, but no such
luck.
My current system is based on 2.4.27 (gcc 3.3.1).and I haven't found any
clear info yet on how to upgrade to 2.6 otherwise I would just try to
upgrade to 2.6 and build a kernel with some printk's.

Are you sure that userspace on livecd is not compiled for 586+ CPU ?

No, I am not sure. Thank you for this suggestion - I will find out from the
lfs folks.
