Boot issue on Lenovo 300e - SebastianRoth - 2019-11-06 20:32

We are working on trying to figure out why iPXE is not able to properly chainload the Linux kernel on Lenovo 300e devices. PXE booting into iPXE workes great and downloading the kernel and initrd binaries as well but then it hangs.

We started by adding debug output to the kernel code to see where it hangs and found that it fails on EFI ExitBootServices call. Adding

Code:

DEBUG=efi_warap

we got the following output on screen:

Is there anything we can do about this within iPXE?

you might want to try IRC or the mailinglist, if at all possible get that in text format, maybe network logging can be used to get it dumped.
