please attach the acpidump output of your laptop. It seems that we failed to evaluate SSET method in acpi_pcc_hotkey_resume. cc Harald. Created attachment 24715 [details]
sudo acpidump --output
The ACPI dump (after a fresh reboot without any s2ram)
bug is blocked because it seems that Harald is not active anymore... cc Matthew, who will be the maintainer of all platform drivers. :p Maybe we need someone to volunteer to maintain the panasonic-laptop driver. The only place I can see this stalling is in the call to EC83 (via ECBF, EC0B). Some kind of conflict with the EC driver at resume time? ECST gets set when the _REG method is called, so we shouldn't be following the =0 path. |
