Subject: bizarre system freeze, I need *HELP* !
Date: Mon, 31 May 1999 15:35:36 -0400
Greetings:
[Up-front apology for the cross-posting, but read on and you'll
understand why it's here & there...]
This is very frustrating. Periodically, maybe once or twice a month,
my Linux box emits a little sound from the hard disk and suddenly my
entire system freezes. I thought it was the X server so I upgraded to
the latest XFree86 SVGA server. Then I thought it was my intermittently
dyng CPU cooling fan, so I replaced that too. So I thought things were
going along swimmingly until this morning when it happened again.
I've copied the relevant section from /var/log/messages, and I'm
hoping some guru or wizard can see just where things are going south.
I'm running Red Hat 5.2, kernel 2.0.36, on a P166 with 64 megs RAM.
The video card is an S3-Trio64 board with 2 megs RAM.
Please, can anyone tell me why this lock-up happens ? *Everything*
freezes, no mouse, no workspace switching, no killing the X server, no
keyboard response at all. I am stymied, so any & all assistance will be
vastly appreciated.
Here's the section from /var/log/messages:

Not profound. Opinions without credibility aren't worth the trouble
of reading. People who spend time considering their topics before
venting typically give opinions that are worth considering by their
readers. Mssr. Gilles doesn't fall into that category. He's just
trolling.

So what? He can express all day long, I don't care. If he wants to
have his opinions taken seriously, he needs to talk less, learn more
and think before he writes. You're confusing "respecting his right to
express his opinion" with respecting the opinion he expesses.

you're right. I forgot that linux is really THE kernel and probably
the only one in the world...?
I only need about 20 lines of code, should I really be doomed to
download a bunch of more than 10MBs I never need?

He specifically mentioned directory reading speed:
Linux reads a large group of ~7000 article
files at slightly over twice the speed of FreeBSD.
This would imply a difference in read buffering unless simultaneous
writing is causing a slowdown. The sync vs. async setting would
be more directly involved in write timing.

Subject: How to use HD with more than 1024 cylinders with LILO
Date: Mon, 31 May 1999 08:36:30 +0200
I have SuSE 6.0 and want to use an old HD (Seagate / 720MB)
for LINUX. The partition-manager prints the errormessage that
the bootmanager LILO may eventually not be able to boot from
that disk, because of the 1024cyl limitation.
I have the HD divided into smaller parts and installed LINUX
on the first partition, but LILO failed to boot (no message,
only thausands of 1s and 0s).
If I use the disk in an old computer (other HD surrounding) the
disk is usable. Why, and how can I make it run beside a 6,4GB
harddisk?
Thanks in advance
Patrick.

A few (10-20) lines of the error messages would be helpful. You're also welcome
to send email directly to me, if speed is important in solving this.

No, you don't need a special driver, but you do need
parallel support somewhere. You can have it compiled
into the kernel, or compiled into a module that either
is loaded at boot or that you load later. It seems to
be most common to have it compiled into the kernel.
Type in 'dmesg' at the prompt, piping it through your
favorite filter (like 'less' or 'more'), and look at
the boot messages. A line or two past the Linux
version, you should see information about first the
serial port(s) and then the parallel port(s). Do
you see anything about 'lp0' or 'parport0'? If not,
then you most likely don't have parallel support,
or at least you aren't loading at boot.
Did the 2.0.35 kernel that you're using come from the
MCA Linux Homepage at the dgmicro site? I know for a
fact that parallel support is *not* included in that
kernel. If you're using this one, you'll have to apply
the MCA patch to the standard 2.0.35 source and
recompile.
I can't say anything about the 2.2.9 kernel as I'm
not using it . . . . yet. I'm planning to set up a
system in the near future on which I play with stuff
like this.

Let's say the results depend on 3 files, with modification
dates of 1/5/99, 2/5/99 & 3/5/99 (uk format). I can put a
Last-Modified of 3/5/99 and cache it for as long as it
doesn't change.
