Hi, I'm experiencing a kernel panic with my Atheros Communications Inc. AR5418 802.11abgn Wireless PCI Express Adapter (rev 01) and the ath9k driver. (My exact card is a Dlink DWA-556). I'm getting this with the 2009-07-29 compat-wireless build, and also the driver in the 2.6.30 gentoo-sources kernel. However, i don't seem to be getting this crash with the 2.6.29 gentoo-sources kernel.
I'm using hostapd-0.6.9 to run my card as an access point, using wpa2 and wireless n is enabled, this is bridged to my ethernet. Not sure if you need my whole configuration, but i can go into more detail if need be. (this is my first kernel bug :) This happens quite quickly after boot and brings the entire system down, I had to use a serial cable to get a crash log. Sometimes it's a while before the crash happens, but connecting to the access point, especially with a weak signal, seems to trigger this fairly quickly. Here is the log printed on the console: (this exact log came from 2.6.30 with compat-wireless 2009-07-29) [ 149.515946] IP: [<f84bc79c>] ieee80211_tx_pending+0xca/0x188 [mac80211] [ 149.515946] *pde = 00000000 [ 149.515946] Thread overran stack, or stack corrupted [ 149.515946] Oops: 0002 [#1] SMP [ 149.515946] last sysfs file: /sys/devices/system/cpu/cpu1/online [ 149.515946] Modules linked in: vboxnetadp vboxnetflt vboxdrv ath9k mac80211 a th cfg80211 rfkill_backport [ 149.515946] [ 149.515946] Pid: 0, comm: swapper Not tainted (2.6.30-gentoo-r4 #4) P5L-MX [ 149.515946] EIP: 0060:[<f84bc79c>] EFLAGS: 00010092 CPU: 0 [ 149.515946] EIP is at ieee80211_tx_pending+0xca/0x188 [mac80211] [ 149.515946] EAX: 6148020f EBX: f6430300 ECX: f70766f0 EDX: f70766f0 [ 149.515946] ESI: f6430320 EDI: f70761c0 EBP: c173ff08 ESP: c173fee4 [ 149.515946] DS: 007b ES: 007b FS: 00d8 GS: 0000 SS: 0068 [ 149.515946] Process swapper (pid: 0, ti=c173e000 task=c16bd300 task.ti=c173e0 00) [ 149.515946] Stack: [ 149.515946] 00000000 f70766f0 00000286 00000000 f5cc7b98 c13b39d7 f7076730 0 0000000 [ 149.515946] 00000001 c173ff18 c102cc9e 00000020 c17359d4 c173ff3c c102c886 0 0000009 [ 149.515946] 00000000 00000100 00000014 00000046 00000049 00000010 c173ff48 c 102c950 [ 149.515946] Call Trace: [ 149.515946] [<c13b39d7>] ? net_rx_action+0x91/0x131 [ 149.515946] [<c102cc9e>] ? tasklet_action+0x57/0x9e [ 149.515946] [<c102c886>] ? __do_softirq+0x8e/0x132 [ 149.515946] [<c102c950>] ? do_softirq+0x26/0x2b [ 149.515946] [<c102cb23>] ? irq_exit+0x29/0x5c [ 149.515946] [<c1004444>] ? do_IRQ+0x6d/0x83 [ 149.515946] [<c1003129>] ? common_interrupt+0x29/0x30 [ 149.515946] [<c100855d>] ? mwait_idle+0x66/0x79 [ 149.515946] [<c1001d68>] ? cpu_idle+0x44/0x65 [ 149.515946] [<c146adf7>] ? rest_init+0x53/0x55 [ 149.515946] [<c17457fb>] ? start_kernel+0x2ac/0x2b1 [ 149.515946] [<c174506a>] ? __init_begin+0x6a/0x6f [ 149.515946] Code: 75 1b ba 64 07 00 00 b8 8c 57 4c f8 e8 07 c2 b6 c8 89 d8 e8 4a e7 ee c8 e9 8a 00 00 00 2d a8 03 00 00 89 45 ec 8b 80 44 01 00 00 <f0> ff 80 00 02 00 00 8b 55 e4 8d 47 64 e8 15 b0 fc c8 89 5d f0 [ 149.515946] EIP: [<f84bc79c>] ieee80211_tx_pending+0xca/0x188 [mac80211] SS:E SP 0068:c173fee4 [ 149.515946] CR2: 000000006148040f [ 149.515946] ---[ end trace 4e6c63af98745b54 ]--- [ 149.515946] Kernel panic - not syncing: Fatal exception in interrupt [ 149.515946] Pid: 0, comm: swapper Tainted: G D 2.6.30-gentoo-r4 #4 [ 149.515946] Call Trace: [ 149.515946] [<c1028a0d>] panic+0x3f/0xdf [ 149.515946] [<c14881f9>] oops_end+0x8b/0x9a [ 149.515946] [<c1017745>] no_context+0x10c/0x116 [ 149.515946] [<c10178d2>] __bad_area_nosemaphore+0xe0/0xe8 [ 149.515946] [<c101793e>] bad_area_nosemaphore+0xd/0x10 [ 149.515946] [<c1489187>] do_page_fault+0x102/0x207 [ 149.515946] [<c1489085>] ? do_page_fault+0x0/0x207 [ 149.515946] [<c148795d>] error_code+0x6d/0x74 [ 149.515946] [<c1489085>] ? do_page_fault+0x0/0x207 [ 149.515946] [<f84bc79c>] ? ieee80211_tx_pending+0xca/0x188 [mac80211] [ 149.515946] [<c13b39d7>] ? net_rx_action+0x91/0x131 [ 149.515946] [<c102cc9e>] tasklet_action+0x57/0x9e [ 149.515946] [<c102c886>] __do_softirq+0x8e/0x132 [ 149.515946] [<c102c950>] do_softirq+0x26/0x2b [ 149.515946] [<c102cb23>] irq_exit+0x29/0x5c [ 149.515946] [<c1004444>] do_IRQ+0x6d/0x83 [ 149.515946] [<c1003129>] common_interrupt+0x29/0x30 [ 149.515946] [<c100855d>] ? mwait_idle+0x66/0x79 [ 149.515946] [<c1001d68>] cpu_idle+0x44/0x65 [ 149.515946] [<c146adf7>] rest_init+0x53/0x55 [ 149.515946] [<c17457fb>] start_kernel+0x2ac/0x2b1 [ 149.515946] [<c174506a>] __init_begin+0x6a/0x6f The server this is running on is a Intel core 2 duo e6600 (dual core).
