So it's 1 out of 10 S9i had this error or just 1/1 ? I've just got my hand on 19 S9i and few of them stop hashing board by board in about 30 minutes after power on, reboot or apply setting will bring back hashing power but it doen't last long. Got no clue.

I only have this one S9i. The others are 5 S9's and 4 L3+/L3++s plus one other. Mine stopped hashing with the errors in my OP within the first 15 minutes or so, but it never came back. Once the error came up I never got it to hash again. Starting for an little bit and then dropping - is that maybe a temp, fan speed, or PSU issue? Over temps will obviously stop them from hashing. Fans that are not reporting (dead or bad tach feeds making them look dead). PSU's putting out a bit too small a voltage causing them to fail after a little. Do you have these PIC errors near the bottom of your kernel log?
