Unfortunately, good coding practice dictates completely ignoring the
UEFI specification as far as is possible, since it is full of
poorly-designed garbage such as EFI_HII_CONFIG_ROUTING_PROTOCOL,
EFI_USB_IO_PROTOCOL, the EFI UNDI API, etc. iPXE is not a UEFI-only
application and I really don't want to pollute the codebase with
thousands of acquire/release calls simply to placate the moronic way
that the UEFI specification chooses to handle interrupts.
I suspect the problem may be caused by a missing call to
efi_snp_release() in efi_block_boot(). I haven't had a chance to test
the attached patch yet, but you can give it a go.
I've pushed two TPL-related fixes:
http://git.ipxe.org/ipxe.git/commitdiff/331ac451e
http://git.ipxe.org/ipxe.git/commitdiff/4f362a032
After these fixes, I am able to perform a SAN boot into the UEFI shell,
and I am also able to complete a successful UEFI installation of Fedora
27 to an iSCSI target.
Heinrich: Could you please test and let me know if this fixes iSCSI
booting within U-Boot?
Thanks,
Michael
