PI4 SDHCI REGISTER DUMP

[tinkeringengineer]

I just installed AArch64 on my PI4 and have it booting from USB. I'm getting a repeated SDHCI REGISTER DUMP which from what I've found is due to not having a SD card installed. Is there any way to make this stop other than installing a card? I found a few references that said to add dtparam=sd_poll_once to /boot/config.txt. This doesn't seem to have any impact on the error. Any ideas?

Thanks

I met the same problem. Additional params in /boot/config.txt and kernel parameters does not disable this spam...
