Confirmed my suspicions - it looks like the host is sent more commands than it can handle. We would need many disks to see this issue though, which you have.

So for stable kernels, 6eb045e092ef is not in 5.4 . Next is 5.10, and I suppose it could be simply fixed by setting .host_tagset in scsi host template there.

Thanks,
John

Don: Even though this works for current kernels, what would chances of this getting back-ported to 5.9 or even further?

Otherwise the original patch smartpqi_fix_host_qdepth_limit would correct this issue for older kernels.
