I've had this problem on a twinhead laptop before. The problem occurs
when the PCMCIA module does an interrupt scan (see section 3.3 of the
PCMCIA howto, below).
You can fix it by adding "do_scan=0" to the PCIC_OPTS definition in the
PCMCIA startup script.
There is another method described in the PCMCIA howto, that requires you
to know on which interrupt the problem is occuring. I never bothered to
figure that out - I just went with the do_scan=0 and everything was fine.
I'll paste section 3.3 of the PCMCIA howto here:
=============================================================================
3.3. Interrupt scan failures
Symptoms:
� The system locks up when the PCMCIA drivers are loaded, even with
no cards present.
� The system log shows a successful host controller probe just before
the lock-up, but does not show interrupt probe results.
After identifying the host controller type, the socket driver probes
for free interrupts. The probe involves programming the controller
for each apparently free interrupt, then generating a ``soft''
interrupt, to see if the interrupt can be detected correctly. In some
cases, probing a particular interrupt can interfere with another
system device.
The reason for the probe is to identify interrupts which appear to be
free (i.e., are not reserved by any other Linux device driver), yet
are either not physically wired to the host controller, or are
connected to another device that does not have a driver.
In the system log, a successful probe might look like:
Intel PCIC probe:
TI 1130 CardBus at mem 0x10211000, 2 sockets
...
ISA irqs (scanned) = 5,7,9,10 status change on irq 10
There are two ways to proceed:
� The interrupt probe can be restricted to a list of interrupts using
the irq_list parameter for the socket drivers. For example,
``irq_list=5,9,10'' would limit the scan to three interrupts. All
PCMCIA devices will be restricted to using these interrupts
(assuming they pass the probe). You may need to use trial and
error to find out which interrupts can be safely probed.
� The interrupt probe can be disabled entirely by loading the socket
driver with the ``do_scan=0'' option. In this case, a default
interrupt list will be used, which avoids interrupts already
allocated for other devices.
In either case, the probe options can be specified using the PCIC_OPTS
definition in the PCMCIA startup script, for example:
PCIC_OPTS="irq_list=5,9,10"
It should be noted that /proc/interrupts is completely useless when it
comes to diagnosing interrupt probe problems. The probe is sensible
enough to never attempt to use an interrupt that is already in use by
another Linux driver. So, the PCMCIA drivers are already using all
the information in /proc/interrupts. Depending on system design, an
inactive device can still occupy an interrupt and cause trouble if it
is probed for PCMCIA.

Mount your main disc partition as /mnt and call vi as
/mnt/usr/bin/vi /mnt/etc/silo.conf
Of course, if the two are on seperate partitions, you will need two mount
points.
I *think* this is how I handled this problem, last time I had something
similar.

Reply-To: [EMAIL PROTECTED]
afaik, this can have two explanations:
- the 'talk' program is buggy
- you are having hardware - probably memory - problems.
Since the program worked before, you could try removing (rpm -e) and
re-installing (rpm -i) it.
A very good test of your memory is to re-compile the kernel. If you get a
Sig 11 error, then the hardware is the most probably cause.
http://www.bitwizard.nl/sig11/ is a very good resource on this.
I suppose re-initialising your swap file (swapoff, mkswapfs, swapon - look
at the man-pages for more) might also be a good idea.

A lot depends on whether the overhead of the system justifies its use.
Not all systems are worth the effort in all cases, and I know some folks
who are quite unhappy about the overhead involved in some of the more
complex commercial change-control systems (as an example).

Actually, I think you may be jumping to conclusions.
How can you toss out meaningful criticisms without knowing the actual
process(es) currently being used by the core developers, if any?

The SysV is one of the most complicated to people who come from either
Dos/Windos and/or BSD.
It is built on the idea that there shouldn't be one init script that runs
all, but there should be a special script for every service.
in /etc/rc5.d you will find symbolic links that point to /etc/init (where
the scripts reside) with a starting letter (S or K) and a number.
The scripts themselves respond to simple commands, such as restart, stop,
start (ie /etc/init/httpd restart), and the letter S or K in the
/etc/rc.d/rc5.d shows whether it should be started or killed. The number
stright afterwards sets the order of the events, ie S5inetd will come before
S95httpd (just an example). All K are being run before the S ones start.
When you get to understand the principle of it, you understand that using
SysV is quite simple. If you wish to start under runlevel 3, another new
service which you do not wish to run under runlevel5, you put a symbolic
link in /etc/rc.d/rc3.d/ with a satrting letter S# (# - the order you want
it to run in the init proccess), but you do not put it in /etc/rc.d/rc5.d!
Also, causing a service to be removed from the init process is made by just
deleting the symbolic link in that rc level!
One last comment - You can have as many S95 as you wish, if their order is
of no importance. Quite simple when you get the hang of it.
Unfortunatley, there are few disadvantages, but I will not discuss them in
this letter, since it is meant only to explain the mechanism of init.
Good luck.

My suggestion is to start thinking seriously on changing all pwd, and
checking users shell permissions.
If I were you, I would have also close my machine to any un-especially-used
service, and maybe block the use of the required ones, allowing only known
IP addresses to be used.

In addition to the two massages prior to mine, (to check the HW, and to get
the CD - which is always recommended), I would advise on using few
configuration tools - try running 'linuxconf' (There you can configure
everything - but there are unimportant error massages there the few first
times you use it). There you will be able to set up mouse, network and all.
It's a powerful tool.
The other tool you might like to use is being called Xconfigurator (I might
miss the name a bit, since I don't use it), which is a shell based X
configuration utility.
Setting things up there might help you run the rest of the system (X).
Good luck there.

It depends. If you've statically linked a GPL library against a
non-GPL program, quite possibly. I believe (but can't quite be
entirely sure) that there have been problems with readline in this
respect, at least in the past. There were problems with Bison
(particularly the parser skeleton code) at one stage too, but I know
that these are resolved now and have been for years.
The GPL only plays nicely if all the world is GPL. Opinion is divided
on whether this is a serious license bug or an excellent feature.
