Rocky 8.9 issues with kswapd0

Hey guys,
Hoping you can help. I’ve 8.9 on 2 different pieces of hardware using the exact same image, but one of them is having issues with kswapd0, causing the CPU to spike at 100%, thus rendering the hardware useless!
The hardware I have issues on is this
SDM Slot-In PC Essential - Sharp NEC Display Solutions

but it’s running perfectly on this
Intel® SDM Slot-In PC Standard - Sharp NEC Display Solutions

Hope someone can advise
Thanks in advance
