I have a grub line for ipxe but it's not processing the cmdline as it

Some clues on how to troubleshoot this issue?
While I don't have any sound troubleshooting advise for you, I am
curious if the following commit may have broke something (for you).
My git-fu is non existent, but I am curious if you were to roll back
previous to that commit, if it would change anything.
Also, since it appears relevant to your use, it might indicate where
you can add some extra debug information to see what's going on.
Mind you, I am a lurker/tinkerer. Doing as I suggest may very well kill
your [cat|dog|fish|child|significant other].

[prefix] Cope with BOOT_IMAGE= anywhere within command line
Some bootloaders seem to add "BOOT_IMAGE=..." at the end of the
command line; some at the start. Cope with either variation.
...
Woo-hoo! What a nice feature. :)
One of the files involved is ipxe/src/arch/i386/core/cmdline.c. Your
screen-shot, Larry, shows:
CMDLINE found ""
which is a message that comes before the "BOOT_IMAGE=..." stripping.
It might be interesting to add some temporary debugging code to show the
'len':
static void cmdline_init ( void ) {
...
size_t len;
/* Do nothing if no command line was specified */
if ( ! cmdline_phys ) {
DBGC ( image, "CMDLINE found no command line\n" );
return;
}
cmdline_user = phys_to_user ( cmdline_phys );
len = ( strlen_user ( cmdline_user, 0 ) + 1 /* NUL */ );
DBGC ( image, "CMDLINE is %zd bytes\n", len );
/* Allocate and copy command line */
...
However I would guess that it'd show 0.
What version of GRUB and does a simple commandline work?:
kernel /ipxe.lkrn config
