msi prestige 13 ai evo laptop intel ultra 7-155h

Dear Arch hakers,

I installed Arch, as on my old laptop but I experience several random slowdowns .

Booting is often very slow, sometimes strangely fast while more often it takes forever.

The same goes for Apps, sometimes they start quickly and I experience no problems.

Other times they freeze for several seconds before unlocking and starting.

Here a video where I compare boot of my old i7 8th gen (left) with my new laptop Ultra 155h (right)

Kernel version: Linux msi 6.10.7-arch1-1 #1 SMP PREEMPT_DYNAMIC Thu, 29 Aug 2024 16:48:57 +0000 x86_64 GNU/Linux

Here my journalctl, kernel loaded modules, pci devices and usb devices

Any other information that can help you helping me just ask

Looks like problem was caused by Intel Volume Management Device (Intel VMD).

Disabling VMD totally solved the problem. Could be a bug in kernel VMD driver?

P.S. To disable VMD from bios, you need to enable MSI advanced bios mode. To do that you need to holding down l-alt (or r-alt, not sure), r-ctrl, r-shift, then F2.
