4.10-rcX kernels hang at boot-up #1

Closed Miouyouyou closed 7 years ago

Miouyouyou commented 7 years ago

Ziyuan Xu patch solved the problem. I was completely mistaken about the cause. The real cause was the MMC driver that broke during some of the 4.10 patches.

This problem is now solved but the MMC is now extremely noisy. I'll open up a new ticket on this subject.
