--- Comment #20 from Lee, Chun-Yi <[email protected]> --- (In reply to Marius Tolzmann from comment #0) [...snip] > > [ 0.000552] ACPI: Core revision 20131115 > [ 0.007292] ACPI: All ACPI Tables successfully acquired > [ 0.049357] ACPI Error: Hardware did not enter ACPI mode > (20131115/evxfevnt-113) > [ 0.049710] ACPI Warning: AcpiEnable failed (20131115/utxfinit-161) > [ 0.049977] ACPI: Unable to enable ACPI The above error message indicate the SCI_EN bit didn't set by the hardware platform and kernel already wait 3 seconds for hardware setting SCI_EN. That means no SCI interrupt will occur. The position of acpi_early_init() before and after changed: start_kernel(void) { [...snip] anon_vma_init(); acpi_early_init(); <=== current position #ifdef CONFIG_X86 if (efi_enabled(EFI_RUNTIME_SERVICES)) /* legacy BIOS in this case, no EFI */ efi_enter_virtual_mode(); #endif #ifdef CONFIG_X86_ESPFIX64 /* Should be run before the first non-init thread is created */ init_espfix_bsp(); #endif thread_info_cache_init(); cred_init(); fork_init(); proc_caches_init(); buffer_init(); key_init(); security_init(); dbg_late_init(); vfs_caches_init(totalram_pages); signals_init(); /* rootfs populating might need page-writeback */ page_writeback_init(); proc_root_init(); nsfs_init(); cpuset_init(); cgroup_init(); taskstats_init_early(); delayacct_init(); check_bugs(); /* acpi_early_init(); */ /* before LAPIC and SMP init */ <=== original position sfi_init_late(); After a quick glance, honestly I didn't see dubious function call between old and new position. -- You are receiving this mail because: You are watching the assignee of the bug. ------------------------------------------------------------------------------ One dashboard for servers and applications across Physical-Virtual-Cloud Widest out-of-the-box monitoring support with 50+ applications Performance metrics, stats and reports that give you Actionable Insights Deep dive visibility with transaction tracing using APM Insight. http://ad.doubleclick.net/ddm/clk/290420510;117567292;y _______________________________________________ acpi-bugzilla mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/acpi-bugzilla
