Hi, I suggest you try it against 6.14-rc3 mainline, and see if you still experience the issue.
If you do, I think you should rebase your patch ontop of 6.14-rc3 and write to the ICE maintainers. >From your 6.14-rc3 git repo: $ scripts/get_maintainer.pl drivers/net/ethernet/intel/ice/ice_main.c Will show you all the correct email addresses and mailing lists.

Upon investigation, we identified a problem in the process that updates the transmit and receive ring statistics in the ice driver. This issue occurs when the counter update process is executed simultaneously on different CPU cores. We have attached a patch to fix this issue. The function ice_update_vsi_ring_stats takes a pointer to a struct ice_vsi as an argument. This structure is allocated on the heap and shared across all CPU cores. The function resets the counter values to zero and then accumulates the values from each ring of the NIC. However, since struct ice_vsi is shared across all CPU cores, the following race condition can occur when ice_update_vsi_ring_stats is executed simultaneously on different CPUs: 1. Multiple CPU cores reset the counter values in struct ice_vsi to zero at the same time. 2. Each CPU core independently increments the counter values. As a result, the counter values may be updated to a higher-than-actual value. The attached patch modifies the implementation to store the counter values on the stack, initialize them to zero, increment them with the values from each ring, and finally update struct ice_vsi. By avoiding the use of shared data for intermediate calculations, this fix prevents the issue.
