(1) System running X freezes. For obvious reasons (all I can do is reset),
no problem documentation is available. This seems to be happening
several times a day. Contrast: my system, running kernel 1.3.42, was
up and connected to the net when we went on vacation. It stayed up
for three weeks and was pretty functional when we came back. So, you
can see that a Linux kernel that crashes in less than a month obviously
has something wrong with it.... ;)
(2) Situation in which I lose most of my network function. Pings still
work, and xntpd works. IRC and POP do not. The last time this
happened, I did a tcpdump and discovered lots of checksum errors, none
of them on ntp traffic. It looked as if ALL of my TCP traffic came
in with checksum errors. I'd start up an IRC client and get a timeout
on each server to which it tried to connect. Unfortunately, I did not
manage to capture the output.
Anyway, as you can see I have minimum documentation, yet I thought it would
be a good idea to mention the problems. Things are probably not ready for
prime-time. Anyone who has any suggestions on how to capture error
information for case (1), please speak up. :)
What follows is my /usr/src/linux/.config, for reference. After that, the
local patches I'm running, all of which are pretty old and stable and none
of which is any major consequence....
