The script checks the FADT to determine if the system supports S0ix and it found that it didn't which is weird since Thomas is setting "mem_sleep" to "deep" from the default "s2idle" which is based on this bit. Here are the commands to check it. sudo acpidump -n FADT -b iasl -d facp.dat grep "Low Power S0 Idle" facp.dsl Thomas, can you confirm what the value of mem_sleep is when you boot and run the above to confirm what your hardware supports? > > > additionally, it encounters a syntax error: > > ./s0ix-selftest-tool.sh: line 1182: wc:: syntax error in expression (error > > token is ":") > > @David, do you know what might be the issue? Yes. The latest kernel changes the output of the ltr_show command by adding a PMC number prefix (since Meteor Lake has more than one PMC now). The script is erring on the unexpected colon.
