After upgrading platform of my home storage server to MoBo with M.2 socket and enough PCIe (though only 3.0) lines, I've added new (unused) AData Legend 960 NVMe SSD as L2ARC (this SSD has best-in-class sustained write performance, when it is full).
Almost immediately I get live lock related to ZFS (with "z_rd_int_%d" thread consume 100% of one thread). It repeats twice.
No errors related to nvme are shown, `smartctl` shows no errors. But looks like it is rather unique problem, as I can not google something like this.
Are somebody know about problems with this SSD on FreeBSD?
Are somebody know about ZFS problem like this?
My system is 13.2-STABLE FreeBSD 13.2-STABLE stable/13-n256849-05c55eed44e5
