AA DISTRIB_REVISION="r38621" In the past few days i may have stumble on a possible kernel bug that has effect on AR9xxx
From all routers that i have been using to test the compiled images only 3 fully works apparently without problems while the others end up by freezing after some time. The difference between the working ones and the malfunctioning ones is the chip. Routers affected : DIR-615-C1 (Atheros AR9130) and TL-WR841N 8.3 (AR9341 SoC) Router NOT affected: Dir 601 A1 (Atheros AR7240 rev 2) Dir 615 E1 ((Atheros AR7240) Dir 615 E3 ((Atheros AR7240) Tp-link tl wr703 The only errors i can obtain from any logs before i completely lose serial console access and the router freezes are: 395.830000] SysRq : HELP : loglevel(0-9) reBoot Crash terminate-all-tasks(E) memory-full-oom-kill(F) kill-all-tasks(I) thaw-filesystems(J) show-memory-usage(M) nice-all-RT-tasks(N) powerOff show-registers(P) show-all-timers(Q) Sync show-task-states(T) Unmount show-blocked-tasks(W) [ 395.860000] SysRq : Show Regs [ 395.860000] Cpu 0 [ 395.860000] $ 0 : 00000000 80320000 80063340 802c8000 [ 395.860000] $ 4 : 00000000 00000000 1000f400 ffff00fe [ 395.860000] $ 8 : 00000000 0000f400 00000000 81ab0000 [ 395.860000] $12 : 80e3a1e4 00000001 00010000 00470000 [ 395.860000] $16 : 80320000 80320000 80310000 80311ca1 [ 395.860000] $20 : 802d0000 00000000 81ff0000 00000000 [ 395.860000] $24 : 004764b8 80095220 [ 395.860000] $28 : 802c8000 802c9ed0 81ff0000 80064ba8 [ 395.860000] Hi : 0000005c [ 395.860000] Lo : 2b183d00 [ 395.860000] epc : 80063360 0x80063360 [ 395.860000] Tainted: G O [ 395.860000] ra : 80064ba8 0x80064ba8 [ 395.860000] Status: 1000f403 KERNEL EXL IE [ 395.860000] Cause : 00804000 [ 395.860000] PrId : 00019374 (MIPS 24Kc) [ 396.080000] SysRq : HELP : loglevel(0-9) reBoot Crash terminate-all-tasks(E) memory-full-oom-kill(F) kill-all-tasks(I) thaw-filesystems(J) show-memory-usage(M) nice-all-RT-tasks(N) powerOff show-registers(P) show-all-timers(Q) Sync show-task-states(T) Unmount show-blocked-tasks(W) Related links: https://bugzilla.kernel.org/show_bug.cgi?id=47741 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/984273 Just like this one: https://forums.gentoo.org/viewtopic-t-801565-view-previous.html?sid=cf2b78f9e57bf60c9e80057332a367ad Also get these: [12891.190000] net_ratelimit: 23 callbacks suppressed [12896.200000] net_ratelimit: 4608 callbacks suppressed [46741.060000] net_ratelimit: 3 callbacks suppressed I am willing to test patches and or fixes for this issue if anyone has any feedback regarding this problem. I was not able to find much helpful information about it. I would also like to know if anyone else is using the same AA revision (or close) with the same atheros chip and gets the same problem. -- Site: http://wirelesspt.net Mesh: http://tinyurl.com/wirelesspt Admin: http://wirelesspt.net/wiki/Cmsv Twitter: http://twitter.com/wirelesspt Youtube: https://youtube.com/wirelesspt Suporte técnico via sms: 91 19 11 798 Donativos/Paypal: http://tinyurl.com/doar-verba Chave publica PGP/SSH: http://wirelesspt.net/arquivos/pk Licença deste conteúdo: https://creativecommons.org/licenses/by-nc-sa/3.0/pt/ Email assinado digitalmente pelo emissor assegurando autenticidade
