6fb8ddd36bde MdeModulePkg/AtaAtapiPassThru: disable the device at ExitBootServices() Prior to this commit, it took 34s for me to go from EFI shell to first install screen. With this commit, it takes 8.5 minutes. I tried to complete an install in this mode but gave up after an hour w/ the installer hung at 10% in "preparing files for install." -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1725560 Title: OVMF UEFI firmware causes Windows 10 w/ GPU passthrough to not boot after upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/edk2/+bug/1725560/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
