Do you use your sd card for this install? Tested if removing it fixes these errors? Or just an empty card reader? The errors are quite common for card readers, with several options listed to try and fix, some suggest using a different sd card might help/holding the card to make sure it makes proper contact, others mention loading with debug_quirks:
rmmod sdhci_pci
rmmod sdhci
modprobe sdhci debug_quirks2="0x80000000"
modprobe sdhci_pci
