Currently debugging a nasty issue with kernel+disk controller-combo.
It seems when there’s a PCIe-NVMe -device controlled by Broadcom SAS38xx -controller (currently using a model from SMC, with it’s latest fw) – the controller firmware eventually hangs and writes garbage to the disks.
How it’s visible in dmesg?
