Boot failure, flood of these messages: ACPI Exception: AE_AML_MUTEX_ORDER, while evaluating GPE method [_L1C] (20140214/evgpe-580) ACPI Error: Method parse/execution failed [\GPE._L1C] (Node f5e0c9a8), AE_AML_MUTEX_ORDER (20140214/psparse-536) ACPI Error: Cannot acquire Mutex for method [SX30], current SyncLevel is too large (1) (20140214/dsmethod-362) ACPI Exception: AE_AML_MUTEX_ORDER, while evaluating GPE method [_L1C] (20140214/evgpe-580) With acpi_no_auto_serialize things look good. Before I tried that option, a bisection led me to remove "| AML_CREATE" from commit f56b05bd111b. That made the laptop boot, things seemed okay, except for the battery not being detected: the normal battery line was gone ("ACPI: Battery Slot [BAT0] (battery present)") and there's this instead: ACPI Error: Cannot acquire Mutex for method [SX45], current SyncLevel is too large (1) (20140214/dsmethod-362) ACPI Error: Method parse/execution failed [\_SB_.BIF_] (Node f5c250d8), AE_AML_MUTEX_ORDER (20140214/psparse-536) ACPI Error: Method parse/execution failed [\_SB_.BAT0._BIF] (Node f5c25168), AE_AML_MUTEX_ORDER (20140214/psparse-536) ACPI Exception: AE_AML_MUTEX_ORDER, Evaluating _BIF (20140214/battery-416) -- Sabrina
