Without some kind of log, this report is pretty useless. Really, it's useless to report kernel bugs here, anyway.

Duly noted @Scimmia, cheers.

anyway you need to do more investigations in order to find what went wrong in kernel 4.1.6,

the best method is to do a "git bisect", in order to find the faulty git commit :

http://git-scm.com/docs/git-bisect

using ccache can speed up the compilation time ( this feature can be enabled in makepkg.conf file ) :

https://www.archlinux.org/packages/community/x86_64/ccache/

you can compile each kernel version with "makepkg" ( with prefix name : linux_custom, you can set it in the pkgbuild file ),

when you will find the faulty commit you have to create a bugreport on the kernel's bugzilla in order to warn the kernel developers

Thanks for the info patrick

seems it is HW specific as that kernel installed fine on intel based laptop.

I got the same behaviour on my X201 ThinkPad. After booting there were only a few kernel-mods loaded. There were no errors in the log-files (journalctl -b). Downgrade to 4.1.5-1 fixed it.

Damn!! While trying to configure grub for the linux-git kernel from AUR, i recognized that my boot-partition was not mounted. That explains why my mods were not loaded on boot after the 'pacman -Syu'. Old kernel with new mods doesn't work :)

I installed arch via the evo-boot image. Either I missed the part to configure the fstab or the script does'nt add the boot-partition to the fstab.

If anyone else got this error, please check if your boot-partition was mounted well during kernel update. cirrus please check your boot-partiton (execute 'mount | grep /boot' in a shell. if there is no output you have the same problem like me)

Can any of the people with this issue report if it is no longer an issue with the most recent Arch Linux kernel? Please let me know. Thank you.

Michael, or cirrus, are you still seeing this? Let me know if this has been fixed so it can be closed if required.
Comment by cirrus (cirrus) - Wednesday, 29 June 2016, 18:21 GMT
Samantha, I'm no longer using 4.1.6-1 and i've not seen this behaviour since 4.1.6-1 got updated.
