Brand new HP z420 (freezing at boot command Red Hat 5 kernels)

[Torgeir]

Hi!

I am chainloading an iPXE linux-kernel v 1.0.0+ (09cc) from pxelinux.

I have som troubles with a brand new HP z420.
I can run these commands (no script), and it is freezing.

PHP Code:

dhcp
kernel tftp://tftp-server/vmlinuz_rhws5u3_x86-64
imgfetch tftp://tftp-server/initrd_rhws5u3_x86-64.img
boot vmlinuz_rhws5u3_x86-64 


(nothing is happening, kernel and initrd is downloading okey, but boot kernel is not doing anything)...

Switched to tftp since we had troubles with http.

With all Red Hat 6 kernels/initrds no problems at all.
Is this because of new hardware? If, is it possible to turn off some dmidecoding in iPXE?

Or some failsafe mode or something like that?

edit: Forgot to mention, the same kernel/initrds (Red Hat 5) is booting fine from pxelinux 4.05... So something with iPXE is freezing.
