[madwifi-tickets] [MadWifi] #496: AP channel wandering in ieee 802.11b mode

#496: AP channel wandering in ieee 802.11b mode --------------------------------------------------------+------------------- Reporter: a<dot>malik<at> unimelb <dot> edu <dot> au | Owner: Type: defect | Status: new Priority: major | Milestone: Component: madwifi: other | Version: Keywords: | Patch_attached: 0 --------------------------------------------------------+------------------- Hi I am using 22-03-2006 ng version. And running the driver on three laptops, dell pentim M. My kernel version on two laptop is 2.6.12 ( FC4) and third one is 2.6.9 ( FC3). I am running some throughput test as well as running some experiments in wireless mode and wanted to measure the throughput for 802.11b network. But to annoying surprise 802.11b is acting in a rude way. After a while ( 1-3 min) the ath0 device disappears ( like when you use ifconfig ath0 down command). And the frequency of the card is wandering from one to another. Same is the case in station mode. So far the problem appear to be only in 802.11b mode. I tried it on all the stations and behaviour of the device appears to be same. regards Malik -- Ticket URL: <http://madwifi.org/ticket/496> MadWifi <http://madwifi.org/> Multiband Atheros Driver for Wireless Fidelity

[madwifi-tickets] Re: [MadWifi] #377: Adhoc mode kernel panic (r1443)

#377: Adhoc mode kernel panic (r1443) -------------------------------------+-------------------------------------- Reporter: punkytse@xxxxxxxxx | Owner: Type: defect | Status: new Priority: blocker | Milestone: Component: madwifi: driver | Version: trunk Resolution: | Keywords: kernel panic Patch_attached: 0 | -------------------------------------+-------------------------------------- Comment (by Vikram): I have noticed this in the r1454 release. The problem does not occur righ away, but after sustained traffic exchange. Not sure if it existed before that. I set up ad-hoc mode in three boxes and run netperf in some combinations. I did this two different times, and the following type of error occured (as extracted from /var/log/messages). I have also posted in [http://madwifi.org/ticket/334] Notice the "ath_uapsd_processtriggers: no skbuff" message was then repeated numerous times; although it says that mysql was terminated. The other machine terminated more programs including mDNSResponser, xfs, X, sendmail, and others {{{ Mar 2 13:12:04 ar83-176 kernel: oom-killer: gfp_mask=0xd2 Mar 2 13:12:04 ar83-176 kernel: Mem-info: Mar 2 13:12:04 ar83-176 kernel: DMA per-cpu: Mar 2 13:12:04 ar83-176 kernel: cpu 0 hot: low 2, high 6, batch 1 Mar 2 13:12:04 ar83-176 kernel: cpu 0 cold: low 0, high 2, batch 1 Mar 2 13:12:04 ar83-176 kernel: Normal per-cpu: Mar 2 13:12:04 ar83-176 kernel: cpu 0 hot: low 62, high 186, batch 31 Mar 2 13:12:04 ar83-176 kernel: cpu 0 cold: low 0, high 62, batch 31 Mar 2 13:12:04 ar83-176 kernel: HighMem per-cpu: empty Mar 2 13:12:04 ar83-176 kernel: Mar 2 13:12:04 ar83-176 kernel: Free pages: 5096kB (0kB HighMem) Mar 2 13:12:04 ar83-176 kernel: Active:517 inactive:905 dirty:0 writeback:229 u nstable:0 free:1274 slab:121087 mapped:23 pagetables:723 Mar 2 13:12:04 ar83-176 kernel: DMA free:2068kB min:88kB low:108kB high:132kB a ctive:4kB inactive:0kB present:16384kB pages_scanned:16 all_unreclaimable? yes Mar 2 13:12:07 ar83-176 kernel: lowmem_reserve[]: 0 495 495 Mar 2 13:12:09 ar83-176 kernel: Normal free:3028kB min:2800kB low:3500kB high:4 200kB active:2064kB inactive:3620kB present:507264kB pages_scanned:525 all_unrec laimable? no Mar 2 13:12:10 ar83-176 kernel: lowmem_reserve[]: 0 0 0 Mar 2 13:12:11 ar83-176 kernel: HighMem free:0kB min:128kB low:160kB high:192kB active:0kB inactive:0kB present:0kB pages_scanned:0 all_unreclaimable? no Mar 2 13:12:11 ar83-176 kernel: lowmem_reserve[]: 0 0 0 Mar 2 13:12:12 ar83-176 kernel: DMA: 1*4kB 0*8kB 1*16kB 0*32kB 0*64kB 0*128kB 0 *256kB 0*512kB 0*1024kB 1*2048kB 0*4096kB = 2068kB Mar 2 13:12:12 ar83-176 kernel: Normal: 37*4kB 10*8kB 5*16kB 3*32kB 5*64kB 0*12 8kB 1*256kB 2*512kB 1*1024kB 0*2048kB 0*4096kB = 3028kB Mar 2 13:12:13 ar83-176 kernel: HighMem: empty Mar 2 13:12:14 ar83-176 kernel: Swap cache: add 23379, delete 23115, find 488/6 58, race 0+0 Mar 2 13:12:14 ar83-176 kernel: Free swap = 959980kB Mar 2 13:12:14 ar83-176 kernel: Total swap = 1048568kB Mar 2 13:12:15 ar83-176 kernel: Free swap: 959980kB Mar 2 13:12:15 ar83-176 kernel: 130912 pages of RAM Mar 2 13:12:16 ar83-176 kernel: 0 pages of HIGHMEM Mar 2 13:12:17 ar83-176 kernel: 2354 reserved pages Mar 2 13:12:17 ar83-176 kernel: 4313 pages shared Mar 2 13:12:18 ar83-176 kernel: 264 pages swap cached Mar 2 13:12:19 ar83-176 kernel: Out of Memory: Killed process 2719 (mysqld).
