How hard is it to run Linux? It depends on your luck and persistence. I received
a junked Lenovo 11e Chromebook recently and it would always freeze at 99% during
any distribution install (classic). Enabling a
[kernel parameter](https://github.com/torvalds/linux/blob/379e4dc5b68a6642fc13b94543be33307ed09704/drivers/mmc/host/sdhci.h#L467)
fixed it. How did I know this? Don't even ask.

#define SDHCI_QUIRK_BROKEN_CQE (1<<17)
(1<<17) = 0x20000
```

sdhci.debug_quirks=0x20000
