[syslinux] Ghostcast random freeze.

[Hudson, Lawrence H.]

Between the time I requested this post and its actual posting I found my problem involved the hardware of the new T410, 510, x201 Lenovo laptops that have released this year. We have over 300 of these machines to build but was experiencing the lock ups. I had recently changed over to the pxelinux right before the new models showed and assumed it was more than likely a pxelinux issue. 

I have not been able to resolve this issue with a dos based boot img. To resolve the issue I created a winpe 3.0 boot.wim which I boot too and image from. I believe the issue to be a hardware conflict with the Lenovo laptops. Using the same dos images which freeze up on the new machines I can image any of my older ones without fault.

If anyone has seen these issues and can guide me on how to resolve this dos base hardware issue with the new Lenovo's that would be great.

Thanks
Loren Hudson

Greetings again,

I am experiencing a lockup when ghost casting about 1 out of 5 client machines locks up.  I don't recall if I was having this issue when I was using 3com pxe menus or not.  I was wondering if the issue I am seeing could be caused by pxelinux since it basically is loading a Linux kernel then booting a MSDos.imz file.  I cannot find any errors from the ghostcast side or the ghost error file.

Here is the pxelinux menu item I am choosing which I created.

# MS-DOS Loader for GHOST Cast Server
LABEL GHOST
MENU DEFAULT
MENU LABEL ^1. T12 Group 1 Session 1
KERNEL MEMDISK
append initrd=imz/t12/T12-G1-1.imz stack=4096 raw keeppxe

I have added the Stack, Raw, and keeppxe settings while trying to diagnose if there was a memory issue with how the imz is loaded up.

Inside the imz file the only important line to mention is the ghost line in the autoexec.bat

GHOST.EXE -FNI -ja=T12-G1-1 -buffersize=32 -sure -rb

I have added the buffersize in hopes it would help with the network card. I have tried -slowfile as well.


Can anyone see anything wrong with what I am trying to do? Has anyone seen random lockups with ghostcast sessions?
