The patch doesn't fix or prevent the oops. Performance might have been better but I did no formal tests. There were no "timeout" messages in the kernel log, however I only ran it with this change for 35-45 minutes. I should mention that in the kernel log, with linux-2.6.8.1-mm4, it complains "process `named' is using obsolete setsockopt SO_BSDCOMPAT". However, with the most recent, 2.6.9-rc4-mm1, it doesn't get that far. A "Unable to handle kernel paging request at virtual address 00017f8c" happens instead. I'm guessing the oops is just killing named before it gets that far. I enabled some more debug options in the kernel and I'm getting a 2nd oops following the first. I wasn't sure if I should paste the huge oops here, and since the raw dmesg also shows spin lock errors, I thought I'd just post both on the web: http://members.cox.net/valenzdu/oops-raw http://members.cox.net/valenzdu/oops-processed I ran it through ksymoops but I don't have a /proc/ksyms and when I tried using /proc/kallsyms it gave me a format error. I hope this is helpful, let me know if there is anything else I can do. (CC me please.)
