Just read help on scsi adaptor driver parameters in kernel configuration -
it says it fails for some reason with tagged que on or whatever else - just
play around with these parameters
Maybe your old kernel had a bit different approach to SCSI bus on your
adapter

One more thought, you could have an unprintable character in the line.
Delete the greentea line and re-type it above the coffee line.

Did you enable the support for the kernel nfsd (search for CONFIG_NFSD
in theconfig file) ? It's under Filesystem->Network File Systems in the
kernel configuration and may be hidden if you didn't enable also Code

Subject: Newbie Boot problems
Date: Tue, 05 Dec 2000 18:46:31 GMT
I apologize if this was double-posted -- not very
co-ordinated today!!
I am a very new user to Linux (I just installed
it yesterday!!) and have run into a bit of a
problem. First a little background on hardware
and the install. I have installed it on a dual
Pentium Pro (2x200mhz)with 256 mb ram. I boot
from a 9.1GB Ultra Wide Quantum Scsi drive
connected to an Adaptec 2940U2W adapter. My video
card is an Imagine 128 (Series 2) with 4mb ram,
and the monitor is a Viewsonic GT770 17".
I first created a 4GB partition with FDISK and
installed Windows98. Next, I proceeded to install
Red Hat Linux 7.0 from bootable CD. I chose a
workstation install WITHOUT manually partitioning
as this seemed to be the most straightforward
install (I'm very new to this!!). The installer
detected my hardware fine, but then crashed when
it got about midway through intstalling the
packages. The error was something like: installer
exited abnormally. I rebooted and tried again and
this time everything went fine, upto the
Xconfigure stage. I chose my monitor (which was
listed), inputed the correct ram for my video
card (4mb) and chose some display seetings I
commonly used, but kept getting a message saying
Xconfigure had failed. Eventually I skipped it
and the install completed. I rebooted and was
presented with a Red Hat screen with boot
options: 1.LINUX 2.LINUX UP 3.DOS (Win98). I
chose 1.LINUX and it began booting. Several
screens of text went by, and then the system hung
at the following: "CHECKING TSC SYNCHRONIZATION
ACROSS CPU'S". I rebooted a couple of times with
the same result. I booted using the second
option, LINUX UP, and booted into the command
shell, and as far as I can tell everything is
fine here. I checked Win98 and that boots fine as
well.
If anyone can offer any assistance, it would be
greatly appreciated. I'm wondering if it has to
do with the fact I have 2 processors, or perhaps
because the xconfigure failed.
Anyways, looking forward to getting Linux
running, as I've heard so many good things about
it. (Even heard people saying they haven't
rebooted a machine in over a year --- can't even
remember a day when I haven't HAD to reboot a
Windows machine!!!)
Sorry if this seems long winded and simplistic,
and thanks in advance for your time and help,
Phil Harvey

millions selling free software
Date: 5 Dec 2000 14:27:01 -0500
This meeting is free and open to the public.
The meeting runs from 6:30 pm to 9:00 pm. After the meeting full and
precise instructions on how to get to our traditional place of refreshment
will be given in clear.
Thanks to support of the IBM Corporation, the meeting is at their building
at 590 Madison Avenue at East 57th Street on the Island of Manhattan.
Enter the building at the corner of Madison and 57th and ask at the desk
for the floor and room number.
Robert B. K. Dewar, Head of Ada Core Technologies, a multi-million-dollar
multi-national free software company, will talk about how to make money
with free software.
Today one of the many rhetorical attacks against free software goes "But is
free software ready for the Enterprise?". Ada Core Technologies sells
services and software built around GNAT, the Official GNU Compiler for Ada,
the Official Computer Language of the United States Military Industrial
Complex. Another rhetorical attack goes "But how can you make money
selling free software?". Ada Core Technologies makes money.
Robert B. K. Dewar is
Professor of Computer Science at the Courant Institute of Mathematical
Sciences at NYU,
an expert on programming languages,
a serious programmer who has written compilers, language libraries and
real-time OSes, on a wide range of platforms from embedded systems to
microcomputers to mainframes,
a mainstay of the robust froup comp.lang.ada,
SPITBOLer extraordinaire,
an effective advocate and amicus at large for free software and the freedom
to program,
and official maintainer of the GNU Ada Compiler GNAT.

Better to implement the script in C using exec calls (but not execlp()
or execvp()) than to use a wrapper to call a script (you're still having
to invoke the shell with uid 0 privileges). You can then either mark the
setuid flag on the binary or use sudo to set up access to the script
(sudo, or an equivalent, being the better choice since you get better
granularity of control as well as logging).
system() is a bad choice for setuid programs, as it executes the program
with "/bin/sh -c" and does not check for the existence of the shell
before executing.

It's unlikely that you need to defrag extfs at all. It's quite a clever
filesystem, and attempts to store files in such away as not to splatter them
all over the place, like DOS or Windoze. In fact, I think I've been warned
before specifically NOT to try and use defrag tools under ext2fs. Not sure
about that last. But I don't think there's any special need to defrag under
ext2fs, anyway.

Now look in /etc/wine/wine.conf, and edit the corresponding values in there.

You can't create a hard-link that crosses devices, but you _can_
create a softlink that will work.

I've just come here with the exact same problem. I'm using RH6.2 and the
2.2.16 kernel - and I think I've discovered what the problem is, but not
how to solve it.
It's to do with this:
> /usr/include/bits/local_lim.h:27: linux/limits.h: No such file or
> directory
Here's line 27 of /usr/include/bits/local_lim.h:
#include <linux/limits.h>
If it's replaced by this
#include "/usr/src/linux-2.2.16/include/linux/limits.h"
the ./configure script runs fine, but then make fails complaining about
a similar "#include <linux/something.h>" line.
So it would seem the compiler's looking in the wrong place for
<linux/something.h> files, yeah? Thing is, I don't know where that's
defined - anyone like to help out?

I just replied to your earlier post under the subject "Problem with

Can anyone tell us both where this is defined?
