Most of the time, it works fine, but about three times in the 6 months I’ve had this machine, resuming from sleep has shown some garbled graphics on the screen, just meaningless lines, doesn’t even look like a corrupted picture, then a few seconds later throwing a kernel panic.
I have a hypothesis that it has to do with full RAM. When it happens, I ask myself “did you have an inordinate amount of browser tabs open” to which the answer is usually yes. But…I’ve got 32GB of RAM, I don’t think it’s THAT inordinate.
Rooting around in journalctl, I see a message that reads:
fedora kernel: Spurious APIC interrupt (vector 0xFF) on CPU#9, should never happen.
Processor 1 through 8 are fine, processor 9 through 15 show that error. This system is a Ryzen 7 7700X (8 core, 16 thread) with a Radeon 7900GRE GPU.
I seem to have 8GB of ZRAM swap. I remember quite a few years ago the wisdom was include as much swap on your system disk as you had RAM, if I understand this is compression-in RAM, I have no swap on any storage media.
Not exactly sure how to troubleshoot this one. Again, most of the time it resumes from sleep just fine, but occasionally it kernel panics.
