6.12.2 Repeatedly Reboots <48hrs

Do you know what time it crashed? The only out of the ordinary thing I see logged are these:

 

2023/07/10 15:37:26.989    Marshall    Error    kernel    Jul 10 15:37:06    Marshall    kernel            i915 0000:00:02.0: [drm] *ERROR* Fault errors on pipe A: 0x00000080

I assume the iGPU is used for Plex? If not you could try blacklisting the i915 driver.

Crash was approximately 18:30 on July 10th.  I was using plex with the iGPU at the time and the stream stopped abruptly.  I logged into the webgui which is noted at 18:31:13.364.

Plex had been in use for an hour or so so those errors at 15:37 were likely when a movie stream had begun.

Probably not practical, but if you can try a couple of days after blacklisting the iGPU driver, of course Plex wouldn't be available. 

Well I double checked and realized I had followed the older guide to implementing the i915 transcoding.  So I've switched to the newer method and if that fails I'll be switching back to blacklisting i915 and using CPU transcoding to test.

Additionally, I checked and Asus has updated the Bios on this board like 3 times since purchase so there may be some stability issue.
