[ipxe-devel] iPXE boot issue which is caused by sharing IRQ

[L***@dell.com]

Hi iPXE developer,

I got an issue about system fails on booting to iPXE server, the message is "No configuration methods succeeded" , error code is 040ee119 (refer to attached screenshot)

I found that the root cause is the Realtek LAN device' IRQ of my client system is sharing with many other devices, like USB controller. But even though, the client system can still boot successfully to MS WDS PXE or IBM Rembo7 server.

I would like to consult with iPXE experts, is it possible to change any setting from iPXE server side to work out this issue without fixing the IRQ sharing issue from client system?

This is an urgent issue to me, I really appreciate if you can reply with comment quickly. Many thanks!

If I'm reading that picture correct you are using commit
https://git.ipxe.org/ipxe.git/26050fd which is from 8 Dec 2016
Please try with latest git master and see if that makes any difference

Which binary of iPXE are you using?
undionly,kpxe reuses the existing PXE stack and is the closest to what
most other NBPs do
ipxe.pxe on the other hand has it's own native drivers for each NIC,
which unloads the existing PXE stack and installs it's own. (this
gives better performance in most cases and also enables additional
features)

Start with testing with latest version of iPXE, also test if you have
different behavior between undionly.kpxe and ipxe.pxe
