As far as the errors from the driver goes, the first one I see is "could not activate Heartbeat timer" (not sure yet what the heartbeat timer does, perhaps expiring peer STAs in the IBSS network when beacons aren't seen for some period). This is printed using some internal logging functions and has the log level LOGP, and any message of this log level will trigger the stack trace.
There's a few ways for enabling the heartbeat timer to fail. The first is that some ACTIVEMODE_OFFLOAD feature is enabled, the second is that the timer hasn't been initialized, and the third is that the actual timer activation fails for any of a variety of reasons. There's no clues in the log about why it failed. However it's also not apparent whether or not failing to activate the heartbeat timer is fatal. The driver just logs the error and continues on. Without digging deeper into the driver I can't tell whether it's the cause for IBSS not working; it could just be a symptom of a larger hardware misconfiguration or even unrelated to the other observed issues. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to wpa in Ubuntu. https://bugs.launchpad.net/bugs/1337753 Title: [mako] can not create an ad-hoc network Status in “linux-mako” package in Ubuntu: New Status in “network-manager” package in Ubuntu: Invalid Status in “wpa” package in Ubuntu: Incomplete Bug description: When trying to create an adhoc network using network-manager with mako kernel "Linux ubuntu-phablet 3.4.0-5-mako #28-Ubuntu SMP PREEMPT Fri Mar 28 15:20:22 UTC 2014 armv7l armv7l armv7l GNU/Linux" the creation fails with: NetworkManager[1347]: <info> Activation (wlan0) starting connection 'Ubuntu hotspot' wpa_supplicant[1735]: wlan0: CTRL-EVENT-SCAN-STARTED kernel: [ 1202.120128] wlan: [1352:E :SME] csrMoveTempScanResultsToMainList: 2908: 11d AP Bssid 00:1e:ab:04:92:77 chan= 1, rssi = -83, countryCode TW kernel: [ 1202.120341] wlan: [1352:E :SME] csrMoveTempScanResultsToMainList: 2908: 11d AP Bssid c8:60:00:dc:42:90 chan= 8, rssi = -66, countryCode GB kernel: [ 1202.120616] wlan: [1352:E :SME] csrMoveTempScanResultsToMainList: 2928: Information about current country Bssid c8:60:00:dc:42:90 chan= 8, rssi = -66, countryCode GB wpa_supplicant[1735]: wlan0: Trying to associate with SSID 'Ubuntu hotspot' NetworkManager[1347]: <info> (wlan0): supplicant interface state: disconnected -> associating kernel: [ 1202.989958] wlan: [1352:E :PE ] limMlmAddBss: 1672: TRYING TO HIDE SSID 0 kernel: [ 1202.990477] wlan: [1352:E :PE ] mlm_add_sta: 1573: GF: 0, ChnlWidth: 0, MimoPS: 0, lsigTXOP: 0, dsssCCK: 0, SGI20: 0, SGI400 kernel: [ 1203.007416] wlan: [1352:F :PE ] limProcessIbssMlmAddBssRsp: 2524: could not activate Heartbeat timer kernel: [ 1203.008087] VOS ASSERT in logDebug Line 219 kernel: [ 1203.008759] ------------[ cut here ]------------ kernel: [ 1203.008850] WARNING: at /build/buildd/linux-mako-3.4.0/drivers/staging/prima/CORE/SYS/legacy/src/utils/src/logApi.c:219 logDebug+0xc0/0xf4() kernel: [ 1203.008881] Modules linked in: kernel: [ 1203.008972] [<c00150d0>] (unwind_backtrace+0x0/0xe8) from [<c08cbf68>] (dump_stack+0x20/0x24) kernel: [ 1203.009033] [<c08cbf68>] (dump_stack+0x20/0x24) from [<c0075628>] (warn_slowpath_common+0x5c/0x74) kernel: [ 1203.009094] [<c0075628>] (warn_slowpath_common+0x5c/0x74) from [<c00756fc>] (warn_slowpath_null+0x2c/0x34) kernel: [ 1203.009186] [<c00756fc>] (warn_slowpath_null+0x2c/0x34) from [<c069aad4>] (logDebug+0xc0/0xf4) kernel: [ 1203.009247] [<c069aad4>] (logDebug+0xc0/0xf4) from [<c05e06cc>] (limLog+0x48/0x50) kernel: [ 1203.009339] [<c05e06cc>] (limLog+0x48/0x50) from [<c05fdce8>] (limProcessMlmAddBssRsp+0x168/0xd40) kernel: [ 1203.009400] [<c05fdce8>] (limProcessMlmAddBssRsp+0x168/0xd40) from [<c05f5010>] (limProcessMessages+0xe74/0x10ac) kernel: [ 1203.009491] [<c05f5010>] (limProcessMessages+0xe74/0x10ac) from [<c05f5560>] (limMessageProcessor+0x274/0x2bc) kernel: [ 1203.009552] [<c05f5560>] (limMessageProcessor+0x274/0x2bc) from [<c05db1a8>] (peProcessMessages+0x54/0x5c) kernel: [ 1203.009613] [<c05db1a8>] (peProcessMessages+0x54/0x5c) from [<c06ba540>] (VosMCThread+0x44c/0x68c) kernel: [ 1203.009705] [<c06ba540>] (VosMCThread+0x44c/0x68c) from [<c0095954>] (kthread+0x9c/0xa8) kernel: [ 1203.009766] [<c0095954>] (kthread+0x9c/0xa8) from [<c000ee74>] (kernel_thread_exit+0x0/0x8) kernel: [ 1203.009827] ---[ end trace 4821fc77d3719675 ]--- NetworkManager[1347]: <warn> Activation (wlan0/wireless): Ad-Hoc network creation took too long, failing activation.
