We are facing an issue with the mcelog service on RHEL, Rocky and Alma 9 vms running on vmware where the mcelog service fails to start and the required edac_mce_amd kernel module cannot be loaded with the error no such device. As per my research and conversations with RHEL support, I was referred to AMD support who referred me to this forum in search of a driver that will allow us to load the kernel module.
mcelog[1102]: mcelog: ERROR: AMD Processor family 25: mcelog does not support this processor. Please use the edac_mce_amd module instead.
