[SOLVED] Kernel booting erratically

I have a problem with my system: As of two days ago, my archlinux kernel boots erratically. Sometimes it works, most frequently it does not. When it fails, I only see "Loading initial ramdisk ..." and nothing happens.  There is no apparent difference between booting the normal linux kernel, the linux-lts kernel or their fallback or recovery images.  Removing the "quiet" option changes nothing.  Removing the intel-ucode before the kernel does not do anything either.

GRUB appears to be fine, the dual boot Windows 7 shows no symptoms.

What can I do to track down this problem?
Any hint is appreciated!

Re: [SOLVED] Kernel booting erratically

You could try using an older kernel (e.g. downgrade your kernel via

pacman -U /var/cache/pacman/linux-...

) to track down if it's a kernel issue.

Re: [SOLVED] Kernel booting erratically

After a downgrade to 4.14.11 and a full pacman -Syu, I am able to boot the current kernel 4.14.15-1.0 as well as the linux-lts-4.9.78-1.0.  The latter did not work the other day.
I have no idea what was broken.  But it is fixed.  Thx!

Re: [SOLVED] Kernel booting erratically

Hmm, maybe something was broken within the packages that has been fixed by now? Purely out of curiosity: Can you examine what package versions are installed now that have not been installed when it was broken? (look into /var/log/pacman.log)
