iPXE blank screen on specific HW

[CyrilP]

Hi !

We used to provision our servers using iPXE and it works flawlessly except for one specific kind of them:

SuperMicro X9DRi-LN4+

iPxe booting is fine using the onboard NIC, but when I try to boot from our 82599ES 10-Gigabit SFI/SFP+,

It leads to a blanc screen if I use undionly.0 and a nice coloroured screen if I use undionly.kpxe.



then



The same card in another server works fine with iPxe.

How to debug this ?

Thanks !
