Stuck at 'loading initial ramdisk' on latest kernel

Hi, latest kernel that boots on my laptop is 6.4.12.
The newer ones (6.4.13 and 6.5.3) block the boot at loading initial ramdisk.
I tried the lts an it boots fine.
Arch is installed since two years on a btrfs filesystem and the vga is an integrated Intel hd 530.
I did some researces finding nothing useful, any help is appreciated.

Have you confirmed the boot is really stuck rather than just the display by examining the journal?  Arch never released a 6.4.13 package where did that come from?

My wrong, you are right, it was 6.5.2 not 6.4.13.
Journal -b doesn't show any error

Re: Stuck at 'loading initial ramdisk' on latest kernel

What if you Disable modesetting?  If that fails try blacklisting i915.  If that fails try adding the following Kernel parameters and see if any more output is produced:

ignore_loglevel earlycon=efifb earlyprintk=vga,keep

Re: Stuck at 'loading initial ramdisk' on latest kernel

Tried adding to 6.5.3 these kernel parameters with no luck:

 nomodeset i915.modeset=0 
 module_blacklist=i915 

Adding

 ignore_loglevel earlycon=efifb earlyprintk=vga,keep 

produces more output but it's incomprehensible to me. There's only a suspicious line that says:
unknown kernel command line parameter "BOOT_IMAGE=/vmlinuz-linux", will be passed to user space

Please post a link to an image of the incomprehensible output.

Probably post your complete system journal for a 6.4.12 boot:

sudo journalctl -b | curl -F 'file=@-' 0x0.st

Is there a BIOS/UEFI update available?

"module_blacklist=nouveau"
Alternatively your GPU is still supported by the nvidia driver.

Probably also add "initcall_blacklist=simpledrm_platform_driver_init" to the https://wiki.archlinux.org/title/Kernel_parameters to get rid of the simpledrm device.

Re: Stuck at 'loading initial ramdisk' on latest kernel

There isn't any bios update.
There is an Nvidia 950m but isn't installed, the Intel igpu is running
Going to try the suggested kernel parameter

Adding

 initcall_blacklist=simpledrm_platform_driver_init 

to 6.5.3 doesn't solve the issue, stuck at loading initial ramdisk

Re: Stuck at 'loading initial ramdisk' on latest kernel

Did you also blacklist nouveau?
The GPU is very much "installed" and addressed by the kernel and nouvau in particular has a track record of stalling the PCI bus…

Re: Stuck at 'loading initial ramdisk' on latest kernel

nouveau is the kernel in-tree driver for nvidia GPUs.

Try "acpi=off"

Probably not.
Does "noapic" [sic!] work?

Something is changed, system boots but it's impossible to login, no input typing the password

What exactly is the environment at this point? A rescue shell? Normal console login? Some graphical DM (GDM etc)?

Do you get away w/ "acpi=noirq"?

"acpi=noirq" doesn't fix
SDDM login

edit: just to inform, sometimes it gets stuck at loading initial ramdisk even running a working kernel and I have to reboot to start the system. It has always done so. Maybe a crappy PC

Re: Stuck at 'loading initial ramdisk' on latest kernel

"rootdelay=5" (waits 5 seconds before trying to mount the root FS
or
"boot_delay=1000", if it boots, that'll be slooooowly

"i8042.dumbkbd" along acpi=off might get you a keyboard and us a journal from an acpi-less boot of the "bad" kernel.
