No issues getting into the iPXE menu typically, the issue only appears to occur once you begin to deploy an image. Occasionally it will give this error while loading the iPXE menu: BzImage… (Connecting) and then loads my standard iPXE menu but with red text and a black background, any function chosen fails beyond this point. I’ve only ever seen this occur on these machines.
I’ve tried kernels from 6.1.22 up to 6.12.25 for testing purposes, the issue remains the same. I think you’re definitely correct with this being an issue with the network adapter not having it’s specific firmware available on the kernels.
The NIC shown in device manager is ‘Intel 82579LM Gigabit Network Connection’ - Hardware ID: PCI\VEN_8086&DEV_1502&SUBSYS_00008006&REV_04
I’ve ran both the commands suggested above while in the debugger and I received a ‘no such file or directory’ error for grep -i -e firm /var/log/syslog but grep -i -e firm /var/log/messages gave me the following output:
fogclient kern.info kernel: Spectre V2 : Enabling Restricted Speculation for firmware calls
I’ve managed to reproduce the issue while loading into the debugger, but when viewing /messages there is no errors apart from the one above.
I hope this helps, if you require any further information please let me know. TIA.
