when serving grub via pxe to thinkpad configuerd to uefi (x86_64-efi), in particular a thinkpad edge e135 with bios version HMET90WW (2.50) and machine type model 335963G), the system immediately reboots when it hits the grub_efi_open_protocol in drivers/efi/efinet.c's open_card function, right where it says "Try to reopen SNP exlusively to close any active MNP protocol instance that may compete for packet polling" in the comment.

as there are no blacklists in grub currently, i'm hard pressed to find the starting points for implementing such a black list.
what are parameters i could query to get anything usable for such a blacklist, like bios vendor plus version number?
