I realize I'm a couple of versions behind, but I thought I'd post this
in case it has not been seen before...I noticed that release 33 was
supposed to fix a couple of (unspecified) network bugs, so this may be
obsolete.
After 4 days of heavy, moderately abusive use (I was using the
userfs.o kernel module) I got the following two oopses logged during
the same second. I did not notice until this morning, when I tried to
telnet to a host on my local ethernet (i.e. apparently nothing else
was affected).
I don't know anything about the networking code, so I have not tried
to narrow this down. ksymoops output follows.
