[HW issue] Iwlwifi firmware crash

Hi everyone, I'm experiencing several errors during boot on my Arch Linux system. The critical one is the Intel Wi-Fi driver (iwlwifi) crashing with a firmware dump, but I also see Bluetooth errors in my logs. The Wi-Fi is functional once the desktop environment loads, but the logs show a continuous loop of timeout waiting for FW reset ACK and NMI_INTERRUPT_UNKNOWN during the kernel initialization phase. I've tried lts, and vanilla kernel, but errors are persistent.

Re: [HW issue] Iwlwifi firmware crash

BT hangs on the wifi chip, kernel won't really matter for firmware crashes - please nevery copy and paste out of a pager (leads to truncated or pre-wrapped lines) and the FW crashes out of context won't really help.
Please post your complete system journal for the boot:

sudo journalctl -b | curl -F 'file=@-' 0x0.st

The FW tries to resets and times out what smells like power saving.

iwlwifi.power_save=0 iwlmvm.power_scheme=1

iw dev <nic> set power_save off

https://wiki.archlinux.org/title/Power_ … interfaces (nb. that article is geared towards increasing power saving, what is not what you want)

Re: [HW issue] Iwlwifi firmware crash

Sorry for the delay. It turns out there was a hardware issue regarding the voltage stability of the card. I've been experiencing problems with the iwlwifi driver due to inconsistent voltage supply to the card. That's nothing more I can do about it. Power saving options didn't work. Should I mark this as SOLVED or?

Re: [HW issue] Iwlwifi firmware crash

"[HW issue]" would be more accurate
