While reviewing the previously collected pstore logs, I noticed a
potentially relevant pattern that may help narrow down the underlying
issue.

Before the kernel panic occurred, gedit repeatedly crashed inside the
same GTK library (libgtk-3.so.0.2409.32).

The recorded sequence was:
- [222.008261] – gedit: segfault at 0xf1
- [5070.588492] – gedit: segfault at 0xf1
- [13621.015160] – gedit: segfault at 0xf1
- [13980.240670] – gedit: segfault at 0x1a
- [14145.102693] – gedit: segfault at 0xf1
- [16906.421869] – Kernel oops: invalid opcode in 
update_blocked_averages+0x111/0x300
- [16906.674732] – Kernel panic: Fatal exception in interrupt
All five gedit crashes occurred in libgtk-3.so.0.2409.32, with several showing 
identical instruction sequences at the fault location.

The subsequent kernel oops occurred on CPU 1 in the scheduler's
update_blocked_averages() function, while executing in interrupt context
(swapper/1).

I have also observed further gedit crashes involving the same GTK
library during later system sessions.

I am not suggesting that gedit itself is responsible for crashing the
kernel. However, the repeated userspace segmentation faults preceding a
fatal kernel exception may indicate an underlying problem affecting
memory integrity or another shared subsystem.

The temporal relationship does not establish causality, but I believe
this pattern is worth investigating, particularly given the recurring
kernel crashes and instability affecting multiple unrelated userspace
applications.

The system is running Ubuntu 24.04 LTS with kernel 6.8.0-147-generic on
an AMD Ryzen 5 2400G (Raven Ridge/Vega graphics).

I am adding this observation to the existing report rather than opening
a separate issue, as a possible connection cannot currently be ruled
out.
