I talked with Thomas Bogendoerfer about the issue and he advised me to test
with the kernel from SLES15sp5 as it has a closer igc driver sources to
upstream.

Even with that kernel the issue is reproduced, log are attached, but does not
have anything relevant on it as well.

The only thing is that with the kernel from SLES15SP5 the problem is less
frequent to happen.

I am trying to reproduce and as soon as I reproduce the issue I will collect
the stack traces from the different tasks with sysrq
