Syslinux - Aug 2004 - Problem: booting stops during "Loading /bzimage...."

Hi 

I'm having problems PXE-booting a Sun-Blade 100x.
As the subject line says, booting stops during "Loading /bzimage...."

PXELINUX 2.06 0x3f46af8 was compiled on an AMD Athlon (not mobile), kernel
2.6.6, bzImage compiled on this system as well.


The 0A940B15 file:

DEFAULT /bzImage
APPEND ip=10.148.11.21 root=/dev/nfs
nfsroot=10.148.11.170:/tftpboot/10.148.11.21 console=ttyS0,9600
SAY Hello from Syslinux


I'm using tftp-hpa-0.34 (on Gentoo Linux), I tried with tftpd from
iputils with the same result.

Am I missing something obvious?
Is there any way to debug this problem?

I would be thankful for any hints.

Regards,
Chris Osicki

It looks like it begins loading the image and then crashes somewhere. 
One possibility is that the PXE stack is "dirty" and uses memory that 
doesn't belong to it (I've seen this before.)  On the other hand
you're
using a fairly modern PXE stack which ought to work.

Where is the cursor, by the way?

The other possibility is that the kernel did load, and something in the 
right-before-the-kernel-runs code trips it up.

Could you try loading a small program like memtest86 or a com32 program 
and see if it loads?

I obviously don't have access to a Sunblade so I can't exactly debug
this...

You may try to update your bios if your network card is onboard or try
to update the pxe bios if it's a standalone one. I saw may buggy pxe rom
:/
You may also try PXELINUX 2.11 :)
