I first experienced the issue on Ubuntu Core 22, but it also reproduces on Ubuntu Core 24 and Ubuntu Server 24.04 with the 6.8.0-50-generic kernel. I am currently paying for snap consulting from Canonical but was advised to file a bug report here for further support. The hardware is intended as production hardware for a commercial IoT gateway product so needs to be very stable. I've seen lots of different error messages when the system crashes which are difficult to capture because I lose access to the terminal, but most seem to relate to a kernel panic or a page fault that can't be handled, e.g. BUG: unable to handle page fault for address: ffffffffc121f1c0 #PF: supervisor read access in kernel mode #PF: error_code(0x0009) - reserved bit violation I've also noticed the system runs very hot. I have not been able to reproduce these issues on the CMCR1ABA i7 (same hardware but Intel Core i7 compute module rather than Intel Core i3). I have carried out a memory test using memtest and there were no errors detected after 12 passes. More details and screenshots of error messages can be found at https://github.com/WebThingsIO/gateway/issues/3174 I've pasted some basic system details below, and the output of the suggested commands for your information. Please let me know if you need any further information. --- Hardware: NUC 11 CMCR1ABA i3 (Austin Beach rugged chassis + Elk Bay compute module) https://simplynuc.co.uk/product/cmcr1aba-i3-elk/ OS: Ubuntu Core 24 Kernel: 6.8.0-50-generic --- $ cat /proc/version_signature Ubuntu 6.8.0-50.51-generic 6.8.12 --- $ sudo pciutils.lspci -vnvn 00:00.0 Host bridge [0600]: Intel Corporation Device [8086:3e35] (rev 0c) DeviceName: Onboard -
