For years now, I've been running a dedicated Quake 3 server on my linux box. Last night, was the first time I've ever seen a core dump with Quake. 2.6.5 was and is now running fine, but under 2.6.6-rc1 it core dumped within about 30 minutes with the attached dmesg output. I am also including my config's for 2.6.5 and 2.6.6-rc1. The only things I'm aware of as being different is CONFIG_POSIX_MQUEUE=y and the relabeling of usbhid (2.6.6-rc1) from just hid (2.6.5). If any additional information is needed, please let me know. Also, please CC as I'm no longer on this mailing list. Thanks, Steve
