Here are attached the requested additional logs.
Sorry for the late answer. This definitely looks like a kernel bug and I
doubt it can be fixed at the Debian installer level. The Debian kernel
team may have more clue and you may consider reassigning the bug to
src:linux.
A quick search with the error messages reports a few possible workarounds:
- Disable Intel AMT (Active Management Technology)
- Disable Windows "fast startup" (hybrid shutdown)
- Disable "fast boot" in BIOS/UEFI settings (not to be confused with
Windows "fast startup")
- Disable BIOS/UEFI settings related to "PCIe Power Saving mode" or
"PCIe ASPM" (Active State Power Management)'.
- Disable BIOS/UEFI Wake-on-LAN
- Power off, remove power cord (and/or battery), hold power button for
30 seconds, then boot.
- Unload + reload kernel module iwlwifi (and iwlmvm if needed)
- echo 1 > "/sys/bus/pci/devices/0000:3a:0.0/reset" (adjust with the
actual PCI bus ID, and maybe unload and reload iwlwifi)
- Add pcie_aspm=off to the kernel command line
- Add acpi_osi=! acpi_osi="Windows 2022" to the kernel command line
- Add a file /etc/modprobe.d/iwlwifi.conf with the following lines:
options iwlwifi bt_coex_active=0
options iwlwifi power_save=0
options iwlwifi uapsd_disable=1
options iwlmvm power_scheme=1
- boot with an older kernel (4.19 from buster, 5.10 from bullseye); it
will not fix the issue but may indicate a possible regression
