Having the same issue of periodic crashes (details from ticket listed in Summary) appear to be same/similar. Unable to determine a consistent action that creates the crash.
- Supermicro 6048R-E1CR24L
- 256GB ECC
- 2 x E5-2680v4
- 2 x NVME (PCIe bus)
Tried modifying VT-d params in BIOS, SR-IOV, IOAT, etc. Was suspicious that virtualization support being enabled (for a bare metal install) may have been part and parcel to the issue. SR-IOV (disabled) seemed to reduce frequency, but still occurs (may be red herring?).
