My specs: CPU i7 6700HQ, Nvidia Geforce 960M, 4k Screen, 16GB RAM, 512GB SSD,
and 2TB HDD (ASUS Laptop N552V).

OpenSUSE TW won’t boot without the “dis_ucode_ldr” kernel boot parameter.

I removed the “quiet” boot kernel parameter to get error output, but
unfortunately, nothing shows up; the boot process stops very early. Even on a
fresh install with default open-source drivers, I’m facing the same issue. So,
it doesn’t seem to be related to the Nvidia drivers.

In fact, openSUSE boots without any issues the first time because the Intel
microcode isn’t installed. But once it’s installed, the boot process hangs.

I’ve tried several rolling distros that use version 6 kernels, they all present
the same problem. Only kernel 6.1.x seems to work with Intel-ucode (tested in
Manjaro).

OpenSUSE Leap (kernel v. 5.x) works fine even when installing ucode. So, I
thought the issue might be with the ucode for TW. I tried copying the microcode
file (06-5e-03) from Leap and replacing the one in TW, following successfully
all the necessary steps to install it manually, but the boot process continues
to hang with no output.

Microcode code for i7 6700HQ is not updated anymore, the latest version is
microcode-20220510.

It’s possible that something broke with kernel versions above 6.1.
