I installed 20310818 on my 4-module batch 1 and 3-module batch 2, and they're both humming along fine. The batch 2 unit runs faster now, reporting WU 1182 now after 15 hours, where before WU was 1161. I think the batch 1 unit does also, though I didn't measure.
If it were me, I would remove the board from the heatsink and reseat it. Maybe exchange it with one in a different position on the same module, and hope it was just a connector problem.
I'd also look at it to see if anything's obviously fried or otherwise damaged.
Same problem here, batch #3 three blade miner:
[match_work_count24] => 0
other worker are fine, but box is hashing 1/24 less
Looking for idea what to check.
