The warning message comes right after I configured the radio and bring it up in adhoc mode. regards, Peizhao On 25/11/10 15:05, Mohammed Shafi wrote: > On Thu, Nov 25, 2010 at 9:27 AM, Peizhao Hu wrote: > >> Hi >> >> I am wondering whether this problem is due to the OpenWRT or an issue of >> the ATH9k. >> >> -----------[ cut here ]------------ >> WARNING: at >> /root/openwrt-svn-repo/routerStation/active_trunk/build_dir/linux-ar71xx_generic/compat-wireless-2010-11-20/drivers/net/wireless/ath/ath9k/recv.c:532 >> ath_stoprecv+0x90/0xa8 [ath9k]() >> Could not stop RX, we could be confusing the DMA engine when we start RX up >> Modules linked in: ath9k ath9k_common ath9k_hw mac80211 ath ohci_hcd >> ath_pci ath_hal(P) nf_nat_tftp nf_conntrack_tftp nf_nat_irc >> nf_conntrack_irc nf_nat_ftp nf_conntrack_ftp ipt_MASQUERADE iptable_nat >> nf_nat xt_NOTRACK iptable_raw xt_state nf_conntrack_ipv4 nf_defrag_ipv4 >> nf_conntrack ehci_hcd ipt_REJECT xt_TCPMSS ipt_LOG xt_comment >> xt_multiport xt_mac xt_limit iptable_mangle iptable_filter ip_tables >> xt_tcpudp x_tables nfs loop lockd sunrpc usbcore nls_base crc_ccitt >> cfg80211 compat arc4 aes_generic deflate ecb cbc leds_gpio >> button_hotplug gpio_buttons input_polldev input_core [last unloaded: ath] >> Call Trace: >> [<800696cc>] dump_stack+0x8/0x34 >> [<8007dedc>] warn_slowpath_common+0x78/0xa4 >> [<8007df90>] warn_slowpath_fmt+0x2c/0x38 >> [<82d075b0>] ath_stoprecv+0x90/0xa8 [ath9k] >> [<82d04138>] ath_set_channel+0xa4/0x740 [ath9k] >> [<82d0503c>] ath_radio_enable+0x55c/0x680 [ath9k] >> [<82f45414>] ieee80211_scan_work+0x30c/0x524 [mac80211] >> [<800910bc>] process_one_work+0x2c0/0x460 >> [<80091d88>] worker_thread+0x240/0x434 >> [<80096a3c>] kthread+0x80/0x8c >> [<8006dde4>] kernel_thread_helper+0x10/0x18 >> >> ---[ end trace 5948ecf07cb92b59 ]--- >> >> >> ------------[ cut here ]------------ >> WARNING: at >> /root/openwrt-svn-repo/routerStationPro/trunk_23933/build_dir/linux-ar71xx_generic/compat-wireless-2010-11-20/drivers/net/wireless/ath/ath9k/recv.c:532 >> ath_stoprecv+0x90/0xa8 [ath9k]() >> Could not stop RX, we could be confusing the DMA engine when we start RX up >> Modules linked in: ath9k ath9k_common ath9k_hw mac80211 ath ohci_hcd >> ath_pci ath_hal(P) nf_nat_tftp nf_conntrack_tftp nf_nat_irc >> nf_conntrack_irc nf_nat_ftp nf_conntrack_ftp xt_string xt_layer7 >> xt_quota xt_pkttype xt_owner ipt_MASQUERADE iptable_nat nf_nat >> xt_NOTRACK iptable_raw xt_state nf_conntrack_ipv4 nf_defrag_ipv4 >> nf_conntrack ehci_hcd ipt_REJECT xt_TCPMSS ipt_LOG xt_comment >> xt_multiport xt_mac xt_limit iptable_mangle iptable_filter ip_tables >> xt_tcpudp x_tables nfs loop lockd sunrpc usbcore ts_fsm ts_bm ts_kmp >> nls_base cfg80211 compat arc4 aes_generic deflate ecb cbc leds_gpio >> button_hotplug gpio_buttons input_polldev input_core [last unloaded: ath] >> Call Trace: >> [<800696cc>] dump_stack+0x8/0x34 >> [<8007df3c>] warn_slowpath_common+0x78/0xa4 >> [<8007dff0>] warn_slowpath_fmt+0x2c/0x38 >> [<869e75b0>] ath_stoprecv+0x90/0xa8 [ath9k] >> [<869e4138>] ath_set_channel+0xa4/0x740 [ath9k] >> [<869e503c>] ath_radio_enable+0x55c/0x680 [ath9k] >> [<87385414>] ieee80211_scan_work+0x30c/0x524 [mac80211] >> [<8009111c>] process_one_work+0x2c0/0x460 >> [<80091de8>] worker_thread+0x240/0x434 >> [<80096a9c>] kthread+0x80/0x8c >> [<8006dde4>] kernel_thread_helper+0x10/0x18 >> >> ---[ end trace d0a293f7237f639f ]--- >> > Under what scenario we are seeing this warning ?,is this still > happening with the latest compat. > >> >> regards >> >> Peizhao >> _______________________________________________ >> ath9k-devel mailing list >> ath9k-devel at lists.ath9k.org >> https://lists.ath9k.org/mailman/listinfo/ath9k-devel >> >>
