Commit aa909462d018 "efi_loader: efi_allocate_pages is too restrictive" causes a failure (synchronous abort) in the command "dhcp zImage" on board p2371-2180 (Jetson TX1). Reverting this commit alone solves the problem. According to the exception dump, elr/pc is in efi_allocate_pages(), which makes sense given the content of the patch. Do you have any ideas? Thanks.
