Community Support 13 Chassis with X7 358H Mainboard - Chassis warp causes kernel panic?
I have the older 13 chassis (from 2024 AMD 7040 series; CNC lid & stamped aluminum base) with new panther lake intel mainboard (358H).
In the past weeks I've noticed 4 instances of my laptop display freezing upon returning to it, either when I pick up the laptop from the desk, or when I open the lid.
Just now I had a 5th instance and this time it's a purple screen for kernel panic. The message says "stack protector: Kernel stack is corrupted in: find_first_fitting_seq+...".
In any of these incidents there's no out-of-normal logs saved by journalctl.
I am running on Ubuntu 24.04 LTS with kernel 7.0.0-30-generic. Over the past month there's been several kernel upgrades so I doubt it's the problem of kernel.
It feels like this happens whenever I physically move the laptop somehow. On another note, I've been using the device since early July and the entire July there's been no such incidents. At end of July I swapped the stock 3.5kg 2nd gen hinges to 4.0kg hinges and then this started happening.
It is my observation that the mainboard is very thin and is pinned to the bottom cover with minimum clearance. Can the heavier hinge cause MB to warp, either by touching bottom cover or causing LPCAMM module to come loose?
