ttm_lru_bulk_move_tail failed  dmesg

This issue seems happened only after hibernation resume and randomly hang after
some times of using.
The attachment starts at 2026-09-03 16:37:10, "BUG: unable to handle page fault
for address: 0000000000002008" then following with "soft lock - CPU#? stuck for
??s".
The GUI screen totally freeze, "caps lock" key works, but Ctrl+Alt+F3 doesn't.
The dmesg records until I long press Power Button.
I had already turn of "Transparent Hugepage support".

My hardware:
Asus ROG Strix G17 2022, G713RM
DRAM: 64G
SSD: 1G+4G
CPU: AMD Ryzen 9 6900HX with Radeon Graphics
Discrete GPU: Nvidia Geforce RTX 3060M with 6G VRAM
OS: Gentoo Linux

What else information should I provide to deal with this issue ?

If this is reproducible without the NVIDIA kernel module?

> Tainted: [O]=OOT_MODULE

If it is, refile here:

There are quite a lot of related reports:
