Kernel Problems: >3.14-4 == modules.devname not found - ignoring

It looks like the Kernel 3.14-5 is broken for me.

whenever I try to update my system stops working. during boot I am dropped in emergancy shell, and the boorloader will not find my harddrive /dev/sdb2

I installed arch linux in uefi mode using gummiboot

this is my fstab:

/dev/sdb1                /boot           vfat    defaults,noatime,discard    0   1
/dev/sdb2               /               ext4            rw,noatime,discard      0 1

this is my gummiboot loading configuration

/boot/loader/entries/arch.conf

title           Arch Linux
linux           /vmlinuz-linux
initrd          /initframes-linux.img
options         root=/dev/sdb2 iommu=pt rw

I hope this looks good, so gummiboot can handle updates normally. Please tell me if I have an error.

after the update, my system wont boot anymore. I can downgrade the kernel without problem (using an arch linux live stick), and my system runs like a charm again.

Is it me or the kernel? I dont know how to localize the problem.

Could this be related to https://bbs.archlinux.org/viewtopic.php?id=179936 ?

Re: Kernel Problems: >3.14-4 == modules.devname not found - ignoring

Could this be related to https://bbs.archlinux.org/viewtopic.php?id=179936 ?

It does not seem to be the same error.
Also the linked sources are not like my error, I think it is my bootloader?

With the new Kernel: 3.14.1-1, I have got the same problems.

Please watch this image:
https://www.dropbox.com/s/fpygehoxk58wb … .05.39.jpg

the file /lib/modules/3.14.1-1-ARCH/modules.devname was present on my system.

I do not know why my bootloader does not find /dev/sdb2. Even if I enter the UUID the error is the same (but with uuid instead of /dev/sdb2)

Re: Kernel Problems: >3.14-4 == modules.devname not found - ignoring

My Error was disused there too:
https://bbs.archlinux.org/viewtopic.php … 7#p1407467

but the provided solution did not solve my Problem.

Warning: /lib/modules/3.14.1-1-ARCH/modules.devname not found - ignoring
ERROR: device '/dev/sdb2' not found Skipping fsck

as mentioned above, I am using "Gummiboot" as a bootloader, because it was recommend in the wiki for UEFI devices

this is still my /boot/loader/entries/arch.conf

title           Arch Linux
linux           /vmlinuz-linux
initrd          /initframes-linux.img
options         root=/dev/sdb2 iommu=pt rw

My /etc/fstab has changed a little:

/dev/sdb1    	/boot		    vfat              defaults    0   1
/dev/sdb2         /         	            ext4      	rw,noatime,discard	0 1
/dev/sda2		/opt		            ext4		defaults 0 1
/dev/sda1		/mnt/programme ntfs		defaults 0 1

(/dev/sdb is a SSD-Drive, tell me if you think my configuration is wrong)

I followed the provided solution my 'ollie' in the linked thread and deleted everything related to mkinitcpio and re-installed it. using pacman -S mkinitcpio linux udev.

I also ran  sudo mkinitcpio -p linux

(which looks good in my eyes)

I cant locate any errors. My system simply does not work.
Using pacman -U in chrooted live USB stick I can downgrade my Kernel to "linux-3.14-4" any time and the System boots again normally.

Please help!
