Quote from: Djokkum on May 23, 2025, 02:20:55 PMI was observing identical symptoms on similar hardware (Shuttle DL30N with Intel N100, 2x2.5GbE Intel i226-LM NICs). After a lot of troubleshooting, it seems the problem caused by RAM. Even though the two specimen of [Crucial CT16G48C40S5](https://www.crucial.com/memory/ddr5/CT16G48C40S5) were not necessarily faulty or out-of-spec for said device, switching to a different model of RAM that was on the list of supported modules for my device resolved the page fault issues. OPNSense has been running for 80 hours now. I never used to pay much mind to those compatibility lists, but it seems these little machines can be picky. Perhaps trying a different model of RAM is also something worth trying for you @rlaace423. Either way, neither OPNSense nor the FreeBSD kernel was the source kernel panics in my case.
I've tested another reliable RAM stick(SK Hynix) and no kernel panic happend for 1 or 2 weeks.
I think this is it. Thank you!
