[RPi5] [linux-rpi-16k-6.12.6-1-aarch64] Kernel panic - not syncing: stack-protector: Kernel stack is corrupted in: __schedule+0xb60/0xb68

[akuropka]

Describe the bug

From time to time system stops with a kernel panic. This should be around since kernel 6.10.

Steps to reproduce the behaviour

Power up the device and wait for sime time.
Additional: one USB-device is mounted with fs=ntfs3, both operations (rsync, smbd) causing the panic are accessing the drive.

Device (s)

Raspberry Pi 5

Additional context

Kernel is based on commit 49679ed (archlinuxarm/PKGBUILDs@195c77a).

I'm not an ntfs3 user, so this may be hard to diagnose. Can you try with kernel=kernel8.img in config.txt? This will force the Pi 5 to use a kernel with a more conventional page size of 4kB.

[akuropka]

Thanks for your idea @pelwell, I switched the kernel to the lower page size but result was the same two days later.
I will be switching to ntfs-3g for testing to see if this has any effect.
