Created attachment 280749 [details] Sleepgraph timeline We run around 3000 iterations of S3 suspend in our weekly stress tests, and we discovered an issue on the Dell Precision 3520. We consistently receive mce hardware errors at a rate of about 33% of the time (once out of each 3 runs). After running mcelog this is the data acquired from a single test run: Hardware event. This is not a software error.
