I'm running CURRENT(12.0-CURRENT #29 r310417: Thu Dec 22 17:06:29 CET 2016 amd64). The laptop is used in the WLAN environment of the campus and at my employer's facility and after booting the laptop, the rarest case is to have a stable connection over the time of work (~4 - 9 hours a day). At this very moment, I receive these messages on the console: [...] acpi_ec0: evaluation of query method _Q26 failed: AE_AML_OPERAND_TYPE wlan0: link state changed to DOWN wlan0: ieee80211_new_state_locked: pending INIT -> SCAN transition lost iwm0: iwm_update_edca: called wlan0: link state changed to UP wlan0: link state changed to DOWN wlan0: ieee80211_new_state_locked: pending INIT -> SCAN transition lost iwm0: add_aux_sta failed iwm0: iwm_send_cmd: acquiring device failed iwm0: could not initiate 2 GHz scan iwm0: iwm_update_edca: called iwm0: iwm_send_cmd: acquiring device failed iwm0: iwm_newstate: could not move to auth state: 16 iwm0: device timeout iwm0: add_aux_sta failed iwm_init_hw failed 35 iwm0: could not initiate 2 GHz scan [...] Ince a couple of days for now, I'm bothered by tons of ACPI messages on the console as well, but I do not know whether they're linked to the problem described above: [...] WARNING: attempt to domain_add(bluetooth) after domainfinalize() iwm0: iwm_update_edca: called wlan0: link state changed to UP ACPI Error: Needed type [Reference], found [Processor] 0xfffff8000461ab80 (20161117/exresop-111) ACPI Exception: AE_AML_OPERAND_TYPE, While resolving operands for [OpcodeName unavailable] (20161117/dswexec-498) ACPI Error: Method parse/execution failed [\134PNTF] (Node 0xfffff80003f17ac0), AE_AML_OPERAND_TYPE (20161117/psparse-560) ACPI Error: Method parse/execution failed [\134_SB.PCI0.LPC.EC.IPCL] (Node 0xfffff80004603f00), AE_AML_OPERAND_TYPE (20161117/psparse-560) ACPI Error: Method parse/execution failed [\134_SB.PCI0.LPC.EC.PCLK] (Node 0xfffff80004604000), AE_AML_OPERAND_TYPE (20161117/psparse-560) ACPI Error: Method parse/execution failed [\134_SB.PCI0.LPC.EC._Q7B] (Node 0xfffff80004604300), AE_AML_OPERAND_TYPE (20161117/psparse-560) acpi_ec0: evaluation of query method _Q7B failed: AE_AML_OPERAND_TYPE error: [drm:pid12:i915_hangcheck_hung] *ERROR* Hangcheck timer elapsed...
