Hi All, I've been involved (a tiny bit) in the EFI stub cleanups which have landed for 5.6, a such I've been building my own test kernels with CONFIG_EFI_DISABLE_PCI_DMA=y up to know that is. Recently I got a Lenovo X1 + Thunderbolt 3 dock for testing and booting my own test kernel build on it failed, disabling CONFIG_EFI_DISABLE_PCI_DMA fixes this. Note currently we have: [hans@x1 master]$ cat configs/fedora/generic/CONFIG_EFI_DISABLE_PCI_DMA # CONFIG_EFI_DISABLE_PCI_DMA is not set So the Fedora 5.6 kernels should work and this is not a bug report, this is mostly a heads up and trying to turn my knowledge that for now turning this on is not a good idea form private knowledge into collective knowledge. I will also report this upstream, so that maybe this issue can be fixed.
