SubjectRe: mm kernel oops with r8169 & named, PREEMPT

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.)
