Part of the reason I am posting this somewhat long message is that my
system has (if memory serves) not crashed since before 1.3.57, and I have
been trying to keep up with new kernels as they come out (not always
successfully - I never got to try .65.) :) I hope this is helpful. Let
me know if I should include any other information in messages like this.
System information: 486sx/33, Slackware 3.0, modular kernel 1.3.66, ELF.
/var/adm/messages: (all of these lines started with "Feb 18 22:" but I have
removed that for more readability.)

Second item: I just got this, one of many problems I have had in trying
to get httpd working. (Did I skip some posts about it not working, or
is it just that I don't have it configured right yet? My aout version worked
fine but I can't get the ELF version to work. Most of the time, it gives me
an "Unexpected network read error; connection aborted." message.)

Third (and last), I thought I'd mention that a couple friends of mine have
crashed under 1.3.64. Here is his description of one of my friends' crash,
and a bit of his (long) messages dump:
The first program to crash was ftp. It GPF'd. (I still have all of the
barf info, but cannot look it up.) Programs were sporadically, but very
frequently barfing. (like 95% of the time) Then kerneld started barfing,
followed by ls, clear, and sync. Then, su barfed, and (several other tiny
programs), and the last program to barf was reboot (shortly after shutdown
did not work), and after displaying a few messages, my system hung. All of
the barfs, as far as I know, were GPFs. Don't have much more than this.
