[solved] Reboot and shutdown hang often

Hello

Arch hangs often when I try to reboot or shut down my laptop.

Here is the journal log of a failed reboot:
https://0x0.st/XzAa.txt

The log mentions watchdog despite I use a kernel parameter to disable it:

$ cat /proc/cmdline
BOOT_IMAGE=/boot/vmlinuz-linux root=UUID=4ca092fc-7430-4ae6-bf4b-68be105f8908 rw loglevel=3 nowatchdog

I have another computer also running Arch, it reboots and shuts down without any problem.

Any idea on what is wrong with Arch installed on my laptop? How to fix it?

Thanks for reading.

Edit:
I have just added another kernel parameter mentioned in the wiki:

$ cat /proc/cmdline
BOOT_IMAGE=/boot/vmlinuz-linux root=UUID=4ca092fc-7430-4ae6-bf4b-68be105f8908 rw loglevel=3 nowatchdog modprobe.blacklist=iTCO_wdt

The problems persist.

Re: [solved] Reboot and shutdown hang often

Here is a new journal log gotten after editing the kernel parameters:
https://0x0.st/XzA4.txt

Before creating this topic, I tested the LTS kernel and the reboot (or shutdown, I do not remember well) hung with it too.

I have 2 ext4 and one ntfs partitions. Both my machines have intel cpu, not amd. The first shutdown failure on my laptop occured on 27th march.

Re: [solved] Reboot and shutdown hang often

You do have a stalled bluetooth call.

mar 30 21:36:56 arch-laptop kernel: Bluetooth: hci0: command 0xfc01 tx timeout

Also you seem to mask wpa_supplicant and run iwd independently of NM, don't.

Re: [solved] Reboot and shutdown hang often

Ok, I have disabled the iwd service, but this did not help. The solution/workaround is my case is downgrade to kernel 6.8.1, because kernel 6.8.2 and even 6.6.23-1 LTS have a bug with intel bluetooth (I use an intel ax200 wi-fi/bluetooth device).

Thank you all for the help.
