Bug#1111027: linux-image-6.12.38+deb13-amd64: HP Gen8: Crashing with 6.12 from trixie, NMI error in IML logs
While leaving it running until it crashes; do dmesg; done; I found a log entry yesterday.
You can also see how it might take five days to crash. The issue came up in older kernels aswell, it is probably some incompatible configuration.
