Hi, I'm using 6.6.x kernel, after I upgraded to kernel 6.12.x for my home server, I got the following error. Which causes soft rdma doesn't work for 6.12.x with my setup.
I read this bug descriptions for several times. To be honest, I am also confused with this problem.
It seems that with 6.6.x kernel, it can work well. And with 6.12.x, it can not work.
So maybe "git bisect" is a good tool to find the commit that causes this problems.
