We have about 6 Servers for this setup and any had their own X520 NIC so it's the same model but not the same card (physically). >> mcelog is empty. The 5018D-MTF Event log has nothing either.

The first line was my "echo h > /proc/sysrq-trigger" then long time nothing and then there was the reset and it started with the new kernel. The earlyprintk options seems to be somewhat silent in comparison with the "console=" option (which I replaced by earlyprintk). There are more kernel messages, like: [43424.885011] Peer xx.xx.xx.xx:23191/80 unexpectedly shrunk window 4088072550:4088072566 (repaired) [44814.276353] perf interrupt took too long (2547 > 2500), lowering kernel.perf_event_max_sample_rate to 50000 Mostly just the shrunk window stuff though, but that's not logged to the serial port. > > Can you try running with no crashkernel option and while you are at > it, please remove the quiet option.
