Borrowed from [joshwiththegoodhair](https://gpd.digital/u/joshwiththegoodhair)

If you’re running into issues in linux where SDHCI debug tables are being printed every couple seconds (and also prevents suspend), it’s because linux believes there is phantom MMC/microSD host. The way to fix this is to blacklist the related modules.

/etc/modprobe.d/blacklist.conf:

```auto
blacklist sdhci
blacklist sdhci_pci
blacklist mmc_core

```

Thanks!! I hope to test this when I receive mine. Suspend is very important to have.
