Arch not booting. Device '/dev/nvme0n1p4' not found.

nikitaevg · 2018-08-26 14:17:04

Hi all!

I have MacBook Air, and I have arch installed on it, without Mac OS. Here is my problem:
Until 4.16 version of linux everything was working. After updating to 4.17 version I got these messages in log while booting:

:: running hook [udev]
:: Triggering uevents...
Waiting 10 seconds for device /dev/nvme0n1p4 ...
ERROR: device '/dev/nvme0n1p4' not found. Skipping fsck.
:: mounting '/dev/nvme0n1p4' on real root
mount: /new_root: no filesystem type specified.
You are now being dropped into an emergency shell.

I've searched in Google for such problem, haven't found any solution, or those solutions weren't working. So I've loaded into liveCD and downgraded the kernel. This worked just fine. But, this is not what I want, I want it to work just fine without those hacks. So, if anyone has any ideas, please, help me. And, this problem remains with 4.18 core. Also, I've tried pacman -Syu after booting in liveCD and chrooting, didn't help.
Here are some information, that might help:

It has something to do with a non-volatile RAM file system. I have not tried Arch on a Mac-Book Air, but it might be that you are booting from non-volatile memory. Sorry I cannot be more help.

The real reason for the post is as a moderator; please change your BBCode 'quote' tags to 'code' tags. Thanks.
