Re: System unbootable after upgrade: unable to find root device.

young lust, that means everything worked as expected.  Congratulations, you've upgraded.  I also saw the permission difference on (at least) one of my machines.  I have a hunch what it is from - but it's harmless.

The pacnew files are also common, see the pacman wiki on what you should do with those.

Re: System unbootable after upgrade: unable to find root device.

This should have nothing to do with UUIDs or modification of the bootloader... so I'm not sure this is the same problem at all. Can you check your UUIDs against what you have in your bootloader?

Re: System unbootable after upgrade: unable to find root device.

Split from /usr upgrade thread as there is nothing to indicate that it is related so far.

The meaning of the word entirely depends on context, but there is very little here so I can't tell if it was just mildly inappropriate or completely inappropriate.

Re: System unbootable after upgrade: unable to find root device.

I am having the same issue. Booting install media and using lsblk shows that the root device is present by the same UUID and it is mountable too. It boots GRUB but stops at the very same message as described in this thread.

Not sure what to do now. Reconfigure GRUB perhaps?

ronnylov, have you tried rebuilding your initramfs?

Re: System unbootable after upgrade: unable to find root device.

When trying to rebuild initramfs I get warning when generating the fallback image:

==> WARNING: Possibly missing firmware for module: aic94xx
==> WARNING: Possibly missing firmware for module: bfa

But generation of images was successful and the system now boots correctly!
Thanks for the help!

Those are warnings not errors.

Re: System unbootable after upgrade: unable to find root device.

Those pacman warnings are just fine. Don't worry about them. My system wasn't booting up. I was stupid enough to close the terminal window before seeing if everything went well after upgrade. So I just chroot my system using latest arch release. But still kernel was not getting upgraded. The problem was with the kmod package. I re-installed it. Kernel upgrade went fine after that.
