The function was introduced by commit eaba51c573a (acpi, acpi_piix, vt82c686: factor out PM1_CNT logic) that forgot to actually call it at piix4 reset time and as result SCI_EN wasn't set as was expected by 6be8cf56bc8b in acpi_only mode. So Windows crashes when it notices that SCI_EN is not set and FADT is not providing information about how to enable it anymore. Reproducer: qemu-system-x86_64 -enable-kvm -M pc-i440fx-6.0,smm=off -cdrom any_windows_10x64.iso Fix it by calling acpi_pm1_cnt_reset() at piix4 reset time. Occasionally this patch adds reset acpi PM related registers on piix4/vt582c686 reset time and de-assert sci. piix4_pm_realize() initializes acpi pm tmr, evt, cnt and gpe. via_pm_realize() initializes acpi pm tmr, evt and cnt. reset them on device reset. pm_reset() in ich9.c correctly calls corresponding reset functions.
