Would it be possible to try https://lore.kernel.org/linuxppc-dev/20210821092419.167454-3-sri...@linux.vnet.ibm.com/t/#u If the above patch is not helping, then can you please collect the output of cat /sys/devices/system/cpu/cpu*/topology/core_siblings Were all the CPUs online at the time of boot? Did we do any CPU online/offline operations post boot? If we did CPU online/offline, can you capture the output just after the boot along with lscpu output.. Since this is being seen on few SOCs, can you summarize the difference between P5040 and P5020. > > [1] https://forum.hyperion-entertainment.com/viewtopic.php?p=53775#p53775 > > > On 09 August 2021 um 02:37 pm, Christian Zigotzky wrote: > > Hi All, > > > > Lscpu reports wrong values [1] since the RC1 of kernel 5.13 on my FSL > > P5040 Cyrus+ board (A-EON AmigaOne X5000).
