kernel .config (5.16-rc3, PowerMac G4 DP)
Get this on my PowerMac G4 DP when I build a kernel with
GCC_PLUGIN_LATENT_ENTROPY=y. The kernel gets decompressed but shortly
afterwards the machine freezes, displaying in black letters on an entirely
white screen:
done
found display : /pci@f0000000/ATY,AlteracParent@10/ATY,Alterac_B@1,
opening...
Same kernel config built without GCC_PLUGIN_LATENT_ENTROPY just boots fine.
Happens on v5.15.5 and v5.16-rc3. I did not test other kernel versions yet.
My Talos II (Power9) on the other hand just works fine with a
GCC_PLUGIN_LATENT_ENTROPY=y built kernel.
