[gPXE] Error booting from iSCSI Target

Hello everyone,

I'm trying to boot a few machines from an iSCSI target (stgt) running
on RHEL5.5, but so far I have not been successful.

I have tested that my iSCSI target is configured correctly, as I am
able to mount the targets from other machines (booted from HD),
and I was also able to install RHEL5.5 directly to the iSCSI target as
well.

I am currently using the latest git tree, but I have tested older
versions but I still was not able to get gPXE to boot.

The debug errors I get are as follows:

My tgtd config is as follows:
<target iqn.2009-02.com.hamzahkhan:Hades>
        backing-store /dev/DiskArray/Hades
        initiator-address 10.254.10.28
</target>

<target iqn.2009-02.com.hamzahkhan:Zeus>
        backing-store /dev/DiskArray/Zeus
        initiator-address 10.254.10.27
</target>

- From what I can tell this is a gPXE problem, not a problem with stgt.
Is this correct?

Regards

Hamzah
