On Fedora (3.5 and 3.6 kernels) we are currently overwhelmed by
tons of iwlwifi warnings at iwlagn_mac_flush() and iwl_dvm_send_cmd()
reports.
iwlagn_mac_flush warning is triggered at:
static inline int iwl_trans_wait_tx_queue_empty(struct iwl_trans *trans)
{
WARN_ONCE(trans->state != IWL_TRANS_FW_ALIVE,
"%s bad state = %d", __func__, trans->state);
return trans->ops->wait_tx_queue_empty(trans);
}
We have 2 instances of this issue:
- started at ieee80211_scan()
https://bugzilla.redhat.com/show_bug.cgi?id=866013
- started at ieee80211_sta_monitor_work()
https://bugzilla.redhat.com/show_bug.cgi?id=861753
iwl_dvm_send_cmd is triggered at:
static inline int iwl_trans_send_cmd(struct iwl_trans *trans,
struct iwl_host_cmd *cmd)
{
WARN_ONCE(trans->state != IWL_TRANS_FW_ALIVE,
"%s bad state = %d", __func__, trans->state);
return trans->ops->send_cmd(trans, cmd);
}
And have 3 instances:
- started at ieee80211_set_disassoc()
https://bugzilla.redhat.com/show_bug.cgi?id=861599
- started at ieee80211_restart_work()
https://bugzilla.redhat.com/show_bug.cgi?id=865072
- started at ieee80211_auth()
https://bugzilla.redhat.com/show_bug.cgi?id=866015
Can those be fixed in some reasonable time ?
I'm not sure if they are related with some user visible problem like
disconnects.
I'll probably revert f0d120af8f55649571c681f49c920b0822050fa5
on Fedora, just to stop getting those warnings ...
