--- Comment #6 from silverducks@altlinux.org ---
Greetings!

I believe I have the same bug on similiar hardware.
Here are the details:

Kernel:
  Version: Linux host-175 7.3.0-rc2 #1 SMP PREEMPT_DYNAMIC
    Wed Sep  9 16:26:06 MSK 2026 x86_64 GNU/Linux
  Git commit/tree:
  Architecture: x86_64
  Distribution: Alt Linux Education 11.2 rc3
  Compiler: GCC 13.2.1
  Kernel command line:
BOOT_IMAGE=/boot/vmlinuz-7.3.0-rc2 \
root=UUID=f35f4c9a-9e09-477f-ae34-33ea09d57042 ro \
resume=/dev/disk/by-uuid/9cb83606-d1a6-4839-b9ff-be22efdf26c3 \
panic=30 no_console_suspend ignore_loglevel

The problem was also reproduced with ALT Linux kernels 7.1, 7.0,
6.19, 6.18, and 6.12. Problem is exactly the same in all cases.

Hardware:
  Motherboard: Gigabyte Z790 X AX Gaming
  BIOS version: F15
  CPU: Intel Core i5-14600K

Failure summary:
  Suspending to S3 (deep) causes the system to hang. The fans and
indicator lights remain on, and the system does not respond to any
input, including short presses of the power button.

Steps to reproduce:
  1. Boot with intel_lpss_pci module loaded
  2. Suspend to S3 (deep)

Attachments (within archive):
  - uname -a, lsmod, complete journal and kernel-only journal of the same
period for upstream kernel 7.3.0-rc2, Alt kernels 7.1, 6.12.
  - Kernel configuration for upstream kernel 7.3.0-rc2, based on the
default ALT Linux kernel configuration with addition of debugging options
and a run through make olddefconfig
  - Kernel module list
  - lspci -vv and lspci -nnk, and list of devices with intel-lpss as driver
  - dmidecode outputs
  - /proc/acpi/wakeup
  - Hardware and firmware information from sysfs
  - os-release
  - kernel command line used

Notes:
  The problem appears related to intel_lpss_pci - when module is
blacklisted, S3 works normally.
  Unbinding intel_lpss_pci from devices or removing it with modprobe -r
just before suspend does NOT prevent the failure.
  S2 (s2idle) and hibernation to disk work fine.
  Failure does NOT occur when booted with init=/bin/bash
  Failure does occur when booted into multi-user.target

Let me know if I should open a new bug instead or if there's any
testing you'd like me to perform.
