Last week I have a problem with kernel update my PPPoE BRAS server from Linux 3.2.0-4-686-pae #1 SMP Debian 3.2.68-1+deb7u1 i686 GNU/Linux to 3.16.0-4-686-pae #1 Debian 3.16.7-ckt11-1+deb8u5. At any time, for no reason, at any load server downed to oops with following trace http://spec.oborona.net/bras_panic
Server software is: rp-pppoe + pppoe + tc htb shapers on ppp interfaces called from ip-ip script. No special settings are not using. I tried to install new debian kernel 4.2.6, but the problem is not solved, everything became worse, server worked with 4.2.6 about 15 minutes and downed to panic (no trace - network rsyslog is empty). After that, i decide to try stable kernel from kernel.org - 4.2.3, and saw the same panic with no network logs as with 4.2.6. Many technical staff from Russia and UA ISP confirmed these problems with ppp in all new kernels (accell-ppp and rp-pppoe). https://translate.google.ru/translate?hl=ru&sl=ru&tl=en&u=http%3A%2F%2Fforum.nag.ru%2Fforum%2Findex.php%3Fshowtopic%3D45266%26st%3D6220 This is the same our problem from UA colleague http://www.spinics.net/lists/netdev/msg352992.html Last kernel with no problem, for me - 3.2.68-1+deb7u1 i686 GNU/Linux. With 3.2 kerel server uptime is infinite. Can i help with additional information? -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
