SSH login fails 5 out of 6 times on my Nighthawk X4S R7800

Hi,
I've the same issue with my R7800. I ran your script with the following results...

Running ipq8065-sqrbug until it fails or 1000 successful iterations
Test iteration 1
ipq8065-sqrbug: Mismatch on Iteration 487 - Index = 125, Byte Offset = 0x01f4
Expected Word = 0x00000000, Actual Word = 0xc0a200a0, &a.dp=0xbef7db40

Currently my R7800 is with 19.07.03. The router runs stable without any issues. Only the ssh login (with putty) requires sometimes several intents.

Did you resolve this issue ?

I've got this same problem on an R7800 running 21.02.
