2012-12-07 08:22:45 TJ description This panic has been occurring intermittently and unpredictably on a gateway/router/WAP server since enabling 802.11n in hostapd which uses a Linksys WMP600N. The server has 6 gigabit and 4 fast ethernet ports, the Wifi, and a xDSL port. The kernel panic was captured over a serial console since the server fails to sync when the manic occurs and no indication is captured in the logs. $ uname -a Linux jeeves 3.2.0-34-generic #53-Ubuntu SMP Thu Nov 15 10:49:02 UTC 2012 i686 i686 i386 GNU/Linux $ lsb_release -a No LSB modules are available.

i386_start_kernel+0xa9/0xaf This panic has been occurring intermittently and unpredictably on a gateway/router/WAP server since enabling 802.11n in hostapd which uses a Linksys WMP600N. The server has 6 gigabit and 4 fast ethernet ports, the Wifi, and a xDSL port. The kernel panic was captured over a serial console since the server fails to sync when the panic occurs and no indication is captured in the logs. $ uname -a Linux jeeves 3.2.0-34-generic #53-Ubuntu SMP Thu Nov 15 10:49:02 UTC 2012 i686 i686 i386 GNU/Linux $ lsb_release -a No LSB modules are available.
