Re: [DUPLICATED] kernel NULL pointer dereference

I also had this same BUG in my dmesg yesterday. I wanted to post my current dmesg but I can't seem to reproduce it anymore.

Re: [DUPLICATED] kernel NULL pointer dereference

sudo journalctl -b -1 | curl -F 'file=@-' 0x0.st

for the system journal of the previous boot

Re: [DUPLICATED] kernel NULL pointer dereference

sudo journalctl -b -1 | curl -F 'file=@-' 0x0.st

for the system journal of the previous boot

It says:
"Specifying boot ID or boot offset has no effect, no persistent journal was found.
451 Unavailable For Legal Reasons"

(I don't have anything in journald.conf but now I remember I have Storage=none in coredump.conf)

Unfortunately I'll have to wait to the BUG to reappear

There're a couple of "6.8.2-arch2-1 doesn't shutdown, reboot or suspend because bluetooth" threads around.
No problem w/ 6.8.2-arch1-1 ?

Just downgraded to 6.8.2-arch1-1 and there's no BUG line in dmesg ATM. Thanks!

EDIT: I spoke too soon... BUG is back at next reboot. It seems to appear randomly.

Sadly not surprising as the only change between the two releases was to Xen networking.
Edit:
https://lore.kernel.org/lkml/CABBYNZKDa … ail.com/t/ which is same fix as I used in https://bbs.archlinux.org/viewtopic.php … 1#p2160941

I'll try with older version and see what happens

I rebooted several times with 6.8.1 and didn't get the BUG line anymore.
It didn't magically fix my reboot issues but I think they're related to nvidia gfx somehow instead of bluetooth, so it's probably a different issue.

Edit: went back to 6.7.9 as with 6.8.1 sometimes Gnome scales incorrectly (all text is smaller than normal)

You might want to open a dedicated thread for that  and post the complete system journal for a 6.8.1 boot there.

Re: [DUPLICATED] kernel NULL pointer dereference

Same problem with
linux 6.8.2.arch2-1
nvidia-open-dkms 550.67-3

It hangs very frequently when reboot and shutdown.

Before that, it doesn't hang. And the bluetooth failures are always there, so it should not be the cause.

Same here. But I also have problems with system freezes when I want to suspend... I will try to investigate.

Re: [DUPLICATED] kernel NULL pointer dereference

I have the same issue. But it is unrelated to the kernel. Either 6.8.1 or 6.8.2 cannot shutdown or reboot due to this kernel NULL pointer bug if I login Plasma 6.0.3. If I click shut down or reboot without login, it shuts down or reboots correctly. If I connect my laptop to its power adapter, then this issue disappears.

Re: [DUPLICATED] kernel NULL pointer dereference

Hi, I already posted this elsewhere (https://bbs.archlinux.org/viewtopic.php … 1#p2161591) but I was told it was not the right place and I think this thread is the good one.

My problem occurs with all my installed kernels :

• linux-lts 6.6.23-1

• linux-zen 6.8.2.zen2-1

• linux 6.8.2.arch2-1

If I shutdown the computer then turn it on again, bluetooth fails to initialize. Also, when bluetooth is not correctly initialized, the command

inxi -F

never ends. When bluetooth is in this failed state, my computer doesn't shutdown correctly, a bunch of lines coresponding to the shutdown procedure is displayed and I have to maintain the power button few seconds to force the shutdown. The next boot is ok after that. So it occurs every 2 reboots. I tested with the 3 different kernels I have. Exact same behavior.

Workaround : I noticed that when I turn off my computer and I unplug the power cable then replug it, then turn my computer on, Bluetooth is initialized correctly every time.

My hardware :
