I'm running 2.0.36 with the patch for ipchains, on an intel Pentium system.
I have been seeing several problems lately, which I did not have before.
The first is a string of kernel faults starting after three days of uptime
(which includes some fairly heavy network and processor usage; this system
is a web server, masquerading router and desktop workstation). The second
happened after less than a day of uptime. Here is the first string of
problems, which eventually resulted in a hung system (very slow death):
