Do you know what they were running before? A bit of a shot in the dark, but the ASID allocator was committed around that time, and contains a workaround for an erratum in the ThunderX. A couple of things to try: - Can you run r354285 (r354286 is the commit in question) on one of the sys= tems and see if the panic is reproducible? - Could you apply the attached patch and grab the dmesg? First let's see if the erratum workaround is getting installed. --=20 You are receiving this mail because: You are the assignee for the bug.=
