Kernel Panic while YouTube

Issues & Assistance
1

Hello, I’ve been using CachyOS for quite a while now and I’m generally very happy with it. However, since August 13th, I’ve had two kernel panics. These occurred on YouTube, once yesterday with Chrome and once today with Firefox.

Version: 6.16.0-7-cachyos

Kernel Panic log:

[ 5344.453264] Kernel panic - not syncing: Fatal exception in interrupt
[ 5344.454364] Kernel Offset: 0xca00000 from 0xffffffff81000000 (relocation range: 0xffffffff80000000-0xffffffffbfffffff)

I got several passes with Mem86+. So I think RAM can be ruled out.

Thx

  • Tainted: [S]=CPU_OUT_OF_SPEC → The kernel detected that the CPU or its configuration might be operating outside officially supported specs. That can happen if you have:
  • Overclocking (CPU/Memory/IFCLK/FCLK)
  • Unstable PBO/XMP settings
  • BIOS features like Curve Optimizer set too aggressively
  • CR2: 0x00007f71593fcaf8 → The faulting memory address. Since this is a double fault, this address may not even be meaningful for debugging.

Common causes for double faults like this

  1. Hardware instability
  • Overclocked or undervolted CPU (Curve Optimizer too negative, PBO settings too high)
  • Unstable RAM/XMP/EXPO profile
  • Weak PSU or sudden power delivery dips
  1. Kernel bugs
  • Since this is cachyos, experimental kernel patches (scheduler, preemption, etc.) can expose edge cases
  • GPU driver (amdgpu) or Wayland compositor bugs causing a bad interrupt handler call
  1. Faulty or marginal hardware
  • Bad RAM (memtest)
  • Overheating VRM or CPU
  1. PCIe device/driver problems
  • AMD GPU reset issues
  • Wi-Fi/Bluetooth firmware bugs (mt7921e has had some)

(having no ideas of my own, just asked chatgpt)
