Kernel panic stack-protector: Kernel stack is corrupted

Hi there, I'm looking for some help with a issue I've been encountering for a week.

I've had this install for about 6 months without any problem and recently started getting Kernel panic messages. One reliable way to get one is to let my laptop suspend after a while. After waking it up, I'm able to login in GDM but then I'll get a blue screen with a QR code and the following message: 

Kernel panic - not syncing: stack-protector: Kernel stack is corrupted in: futex_wait+0x11a/0x120

Full logs from the latest crash available here

I also had random freezes when using my laptop on battery. No error messages, cannot switch to another tty, just totally frozen.

My two guesses are:
- the firmware I'm using for my wifi card broadcom-wl. Mostly because I can spot a few messages in my logs about how it's not officially supported
- overheating: I've recently repasted my GPU and CPU because thermals were terrible while gaming. While this has been a success and I have much better temps I'm thinking maybe this is related somehow?

FWIW I dual boot windows and did encounter a random shutdown recently but nothing else. I use arch mostly for browser/email/messaging apps while I use Windows for music production and gaming so in theory usage is less intense on windows which might rule out the overheating issue.

I would appreciate any pointers, I can't find much with the kernel error message.

Config:
Laptop is Asus G14 2022 (GA402RK)
AMD Ryzen 9 6900HS
AMD Radeon RX 6800S

uname -r:

6.17.9-arch1-1

I get the same issue using the linux-g14 kernel.

Planning to do a memtest tonight but given that I have no issues on Windows I doubt I'll find anything. Any help welcome!

Did you already do a memory check with something like memtest86+?

Re: Kernel panic stack-protector: Kernel stack is corrupted

You may try broadcom-wl-dkms firmware instead of broadcom-wl. You would need to install also linux-headers for dkms.

When did it started? After last update?
You may try to downgrade linux-firmware-amdgpu to 20251111-1 or update to latest linux-firmware 20251125-2 or downgrade amd-ucode.

broadcom-wl is built from broadcom-wl-dkms built against the linux package. How could it have different firmware?

Thanks for the suggestions.

I just did that, 4 passes with 0 error

I actually did that a few days ago even though I had the same though as @loqs and wasn't sure it would change anything

I would say two weeks give or take. I have not encountered the error today as I didn't let my laptop go into suspend or hibernate state so I'll wait until the next kernec panic before I try that in case some other update fixed the issue.

Re: Kernel panic stack-protector: Kernel stack is corrupted

If updates and linux-firmware plus amd-ucode downgrades do not fix the issue I would suggest Downgrading to before the issue started to rule out a software issue.
