@arighi, unfortunately I do not have access to the hardware anymore. As
far as I know, @agrebennikov is working on getting access to some test
machines from the vendor. Once we have it and the problem is still

Hi Andrea, I am not able to access the machines now and run dmesg. But
in the attached sosreport you can find /var/log/kern.log and

Running perf report shows that ker
