MauryG5:
wait let me understand, the command modeprobe blacklist I have to put it in the petit boot so I should get out of the operating system, go back to petit boot, exit the list of initial options and where it allows me to type I have to enter the command modeprobe.blacklist, I got it right?
kmarek:
You start your computer. At first it looks like this while it scans disks:
Then you'll see what it finds and it'll start counting down. Arrow down to your Fedora entry with the asterisk (*)::
Press "e" for edit, it'll take you here to temporarily change it:
You want to change "Boot arguments". Notice that the options are separated by spaces:
So you want to add "modprobe.blacklist=ast video=offb:off" without spaces between the equals. This is wrong:
This is correct:
Go to "OK", press enter:
It'll take you back to the menu, with your change applied (for this boot), press enter:
Let us know if it fixes it. Next step will be to permanently fix the boot arguments.
MauryG5:
ok I immediately try and let you know, thank you very much

btw, just FYI, there's no ttyS0 for serial console on talos/blackbird or any openpower hardware, as the kernel does no see a physical serial port; the correct serial console is hvc0 (without a baudrate, as it's not a serial console per se) for powernv, or hvsi0 (baudrate 19200) for pseries machines.
