[SOLVED]Graphics and ethernet devices not detected after kernel update

Hi Everyone,

I updated my system about a week ago (was a pretty large update, the graphics driver was updated and so was the kernel). After rebooting I could no longer startx. After a shutdown, I started back up and I lost connection to the internet. 

I tried a whole bunch of things to determine what the problem might be, including booting into my install USB. From the USB I was able to detect and connect to the internet so it's probably not hardware related.

The one thing that seemed odd when I was digging around was the kernel was was updated to 4.0.4 but my system is running 4.0.1 or at least Xorg.0.log says I am (also the output from uname -r was 4.0.1). Not sure why I'm not running the new kernel, but I think that might be the reason for my problems.

Can someone tell me why this might have happened, and what I can do to fix it?

Thanks for taking the time to read my post.

Re: [SOLVED]Graphics and ethernet devices not detected after kernel update

Do you have a separate /boot partition and was it mounted during the upgrade?

Re: [SOLVED]Graphics and ethernet devices not detected after kernel update

I do have a separate /boot. I'm not sure, but I believe it was mounted during the upgrade. Is there a reason it would unmount for the upgrade?

Make sure /boot is mounted then re-install the linux package.

If you downgrade your graphics driver (whatever that is) and related packages, does `startx` work again?

Re: [SOLVED]Graphics and ethernet devices not detected after kernel update

Okay, so I reinstalled the linux package with all my devices (except swap) mounted from the USB. And everything works (both ethernet and graphics).

So that's good! But why was /boot not mounted during the upgrade? I shouldn't have to manually mounted every time I do an upgrade?

Thanks for all your help so far!

Re: [SOLVED]Graphics and ethernet devices not detected after kernel update

Is it mounted after reboot?
Else, is it in your fstab?

Good question.

Post the content of /etc/fstab plz.

EDIT: and the output of:

cat /proc/mounts|grep /boot

Here is my fstab:

Here is /proc/mounts:

systemd-1 /boot autofs rw,relatime,fd=30,pgrp=1,timeout=300,minproto=5,maxproto=5,direct 0 0
/dev/sdb2 /boot ext4 rw,relatime,stripe=4,data=ordered 0 0

It is mounted after reboot. The efi partition doesn't appear to be mounted though.

Re: [SOLVED]Graphics and ethernet devices not detected after kernel update

You have two different partitions trying to mount to /boot, of course you're having problems.

I have it set this way based on the Arch Wiki Installation guide:

Using /boot is recommended also for mounting the EFI System Partition on UEFI/GPT system. 

Or should I have another mount point (eg /boot/efi)? And how can I go about changing it post-installation?

Thanks!

Re: [SOLVED]Graphics and ethernet devices not detected after kernel update

Why are they separate in the first place?

Remove the /dev/sdb2 line from your fstab and remove the partition (once you are sure all the files you need are present in /dev/sdb1) so you can free up the space on your drive.
