About new 5.6 CONFIG_EFI_DISABLE_PCI_DMA option
by Hans de Goede
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.
Regards,
Hans

kernel-5.5.0-1.fc32.x86_64 DOA?
by Chris Murphy
Hi,
Two baremetal systems and one VM hang with kernel-5.5.0-1.fc32.x86_64
right after GRUB menu entry selection/timeout for this kernel. Black
screen, menu goes away, I see a white underscore, that's it. Doesn't
recover.
I put GRUB into debug mode and I can see the kernel file being loaded
block by block off the media, but oh man something is off with GRUB
because the text scroll is unbearably slow. So I just had to kill it.
Last working for me is kernel-5.5.0-0.rc6.git1.1.fc32.x86_64.
