Hi,
I've upgraded the system (an asus n752vx laptop with optimus and nvidia driver), but after reboot it hangs loading the ramdisk with the ".. loading initial ramdisk ..." message as the last one.
I've managed to downgrade all the packges and this is the pacman log:

Can you help me, please?

Today I've reinstalled the upgraded packages and I've installed the lts kernel and nvidia driver too.
The 4.14.17-1-lts kernel loads correctly.
The 4.15.1-2 kernel hangs after "loading initial ramdisk" message with no other message.

Any change if you remove nvidia-drm.modeset=1 or blacklist the nvidia driver?

Yesterday I've tried removing all the kernel parameters without success.
I've not tried to blacklist nvidia (Is it possible to blacklist only when I load the 4.15.1-2kernel and keep nvidia on the lts?).

Yes see Kernel_modules#Using_kernel_command_line_2 and only change the boot entry for the linux kernel.

Thanks.
Tomorrow I will try.

Blacklisting nvidia has not resolved the issue.
The new kernel doesn't load.

Just to ensure it is not just a screen issue nothing is recorded in the journal from these failed boots?
If not you could try more kernel options, check the linux 4.15.2-2 update if that fails might have to bisect the kernel see if you can locate the cause of the issue.

I don't think it is a screen issue because the "loading initial ramdisk" remains on the screen, but the system is completely unresponsive (alt+stamp+REISUB does not work).
Even using the emergency option do not solve the problem.

4.15.2-2 update does not boot too.
So at the moment, no 4.15 kernel works on my laptop.

Adding noefi solves the problem.
What does that kernel parameter do?
Is it safe to use the laptop in such a way?
EDIT
the noefi does not solve the problem because only sometimes the system starts.
Moreover sometimes also the lts does not start.
I've checked the EFI boot partition and this is the result:
sudo fsck /dev/sda1
[sudo] password di andreak:
fsck da util-linux 2.31.1
fsck.fat 4.1 (2017-01-24)
0x41: Dirty bit is set. Fs was not properly unmounted and some data may be corrupt.
1) Remove dirty bit
2) No action
? 2
There are differences between boot sector and its backup.
This is mostly harmless. Differences: (offset:original/backup)
65:01/00
1) Copy original to backup
2) Copy backup to original
3) No action
? 3
/dev/sda1: 551 files, 40603/65536 clustersIs the dirty boot partition maybe related?
Should I remove the dirty bit and copy original to backup (answer 1 to both questions)?

Adding the earlyprintk=efi,keep to the boot command I've discovered that 4.15.xxx kernels hang at the following line:
... x86: Booting SMP configuration ... So noefi does nothing to solve the problem and still I can't load a 4.15 kernel.
Any idea?

Today I've tried to add acpi=off to the kernel boot parameters of the 4.15 kernel, because I've seen that the 4.14-LTS kernel report the following line:"Using ACPI (MADT) for SMP configuration information"
So since the 4.15 kernels hang at "Booting SMP configuration", I wanted to see if the problem is ACPI related.
It seems so.
With acpi=off the boot sequence keep going up to the moment moment when the X system should be activated, but then it stops (maybe something in my system doen't work correctly with the acpi=off).
So it seems as if the SMP configuration given by acpi is broken on 4.15 (and my i7-6700HQ).
Should I open a bug in archlinux?
EDIT
I've gone back to use the same kernel parameters I'm using with the 4.14-lts and I've avoided to pass to the 4.15 kernel the intel-ucode image changing this line in the grub.cfg file:
initrd /intel-ucode.img /initramfs-linux.imgto
initrd /initramfs-linux.imgNow the system works perfectly.
I've tried to downgrade the intel-ucode, but system keeps hanging if initdr calls the intel-ucode.img with the newer kernel.
So it seems I've found a workaround, but somehow the system does not work correctly if I try to use intel-ucode and newer kernel.
It seems a weird bug, but I don't know to which package should I refer to open a bug.
