You need either a BIOS update or additional kernel command-line parameters to work around BIOS incompatibilities with linux – for some kernel command-line parameters see:

This issue is not specific to Fedora but to your model’s “BIOS”. I have often found appropriate command-line parameters for a specific model in forums for other linux distros. The dmesg data in the LHDB does include the kernel command-line, but looks like all the Ultra 5 probes only have “detected” for the iGPU.
