[fedora-arm] Re: issue booting Fedora 35 with RPI4


I did a few more tests

     - using USB2+hdmi, boot is fast but with  a long period after the EFI boot when the kernel is selected, the system is coming up after 1 minute or so.
     - using USB3+hdmi, boot is slow with the same long period after the EFI boot but also with a very slow process after the 3 first lines it takes many minutes to go to the next line after "Basic system" line, the system is coming up after a few minutes.
     - using USB2+hdmi with hdmi_force_hotplug=1, same as USB2
     - using USB3+hdmi with hdmi_force_hotplug=1, huge timeout, the system is not booting
    I did not try USB3 without hdmi .. :)

Hello guys,

I have been working on a very strange issue when booting Fedora 35 on RPI4.

I have the issue on 5 different RPI 4 boards, I have tried to swap
power, network cable, network port, network switch, even use a new sd
card/ssd drives....

1/ I use the arm-image-installer with target=rpi4 and the last F35
aarch64 raw image to flash a SD Card.

2/ I boot the new system and it is working fine

3/ I updated the system with dnf -y upgrade

4/ I move the system VG (fedora_fedora) on a SSD drive connected using
USB-SATA converter. and then use "dracut --force" to make the system
working fine.

5/ reboot is ok after that and the system is running well.

I discovered after many tests that when the USB-SATA is connected on one
of the 2 USB2 ports (en the left side) that the system is booting well.

but if you connect on the USB3 ports (between USB2 and ethernet port)
the system is not booting....

but if in this configuration you have a HDMI port connected to a
monitor, then the system is booting well....

to sum up

     USB-SATA    : USB2    => booting ok

     USB-SATA    : USB3    => not booting

Does it work if you add " hdmi_force_hotplug=1" to '/boot/efi/config.txt'?

     USB-SATA    : USB3 + HDMI        : connected to monitor => booting ok

I used theses systems to test ESXI arm edition and everything was
working fine using USB3 ports without any HDMI port used.

I found the following posts
https://forums.raspberrypi.com/viewtopic.php?f=28&t=245323) and tried to
append  "usb_storage.quirks=174c:0825:u" using

grubby --args="usb_storage.quirks=174c:0825:u" --update-kernel

but it seams to have no effect ... the system is not booting

When I plug back the HDMI port, from dmesg I see that

Did I do something wrong, do you have any idea ?
