Details

Description: If booting using efistub (I'm calling it from rEFInd) 5.6.0-arch1-1 fails with:

exit_boot() failed!
efi_main() failed!

passing kernel parameter "efi=no_disable_early_pci_dma" allows it to boot.

Additional info:
* package version(s)
5.6-arch1 (and arch5.6-arch2 if using same config file).

* config and/or log files etc.

This line was added in commit https://git.archlinux.org/svntogit/packages.git/commit/trunk?h=packages/linux&id=3734fe98a51ca7e776052cdabc80be9885b7d40d
+CONFIG_EFI_DISABLE_PCI_DMA=y

* link to upstream bug report, if any
https://bugzilla.kernel.org/show_bug.cgi?id=206789

Steps to reproduce:
Download tag 5.6-arch1 and get config/PKGBUILD using Asp, compile with no changes.

Well, it was worth a try; it will be disabled.

CONFIG_EFI_DISABLE_PCI_DMA=y is still in testing/linux 5.6.2.arch1-1, and that kernel breaks booting on MacBookAir7,2. I'm using systemd-boot.

A workaround is adding efi=no_disable_early_pci_dma to the kernel command line as suggested in the upstream bug report.
