I had problems similiar with this but it was for my CDRW and CDRom if I
enabled DMA access then everytime I tried to write to the writer my whole
system would lock up. I fixed this by disabling DMA for the CD's by adding
a /sbin/hdparm -d0 /dev/hd{c,d} and haven't had a problem yet.
Try disabling DMA for your CDWriter only and see if this helps.
command
hdparm -d0 /dev/YOUR-CDWRITER
Now I have a question I have 2 hard drives both Maxtor 30 Gigs (ATA 66 and
ATA100 but running at 66) a writer and a CDROM what is the "best" way of
arrranging them? I have heard that if I have ATA-66 drives connected with a
CDROM (ATA-33) I will transfer data at the speed of the slowest device on
that particular IDE channel. I also have run into a warning trying to copy
a CD that Nero (running under Wine) says that I could have problems with
copying data using the same IDE channel, While I have not had any problems
I am wondering what is "right".

I have been running an Intel based Linux (Redhat) web server for quite
awhile now, but lately have bumped into some problems that really have me
puzzled. Whenever the machine gets into trouble, I like to go ahead and
reboot it to see if that clears it up. That is when I noticed that it takes
a VERY long time to get through the 'killall' phase of shutdown. We're
talking about way over 5 minutes, maybe closer to 10 minutes.
The next thing I noticed is that when some of my PHP code gets executed that
is doing an 'fopen' on a URL (a socket read essentially), that too takes a
long, long time. About 4 minutes or so.
Finally, I can no longer ftp into the web server using WS-Ftp. I get a
'blocking call cancelled' error. Trying to ftp into it from a DOS prompt
just hangs until it finally comes back with 'Connection closed by remote
host'.
Anyone have ANY ideas where to begin on troubleshooting this problem?

I have a Netgear FA410TC PCMCIA NIC. This is a 10/100 Mbps NIC that I've
currently got running under Linux. I have a 10/100 Mbps switch that
reports the NIC running at 100 Mbps and full-duplex. Linux reports the
same. I'm currently using the NE2000 compatible PCMCIA support kernel
module for the NIC. Everything works fine, except for one tiny detail. I
can't transfer a file to/from the laptop at more than 10 Mbps. What's the
deal? Anyone have a suggestion?
I'm running Debian unstable with a 2.4.5 kernel. Thanks.

Subject: Does xawtv work under XFree86 4.0.1?
Date: Sat, 2 Jun 2001 10:02:26 -0000
I've just loaded XFree86 4.0.1 to my Mandrake7.2 box and cannot now get my
Pinnacle PCTV card to work. It worked fine under my old X3 setup but now I
cannot get a signal. I've checked the modules bttv, i2c and i2c-core are
loaded and no problems there as far as I can tell but when I run the tuning
wizard on kwintv it comes up with nothing as channels found. I've also tried
xawtv and the same problem there so I think it must be X that is causing the
problem as everything seems to be installed ok. I also have the new NVidia
drivers loaded but I can't see that being the problem.
Has anyone got it to work under X4.0.1 and how did you do it? Any help would
be most appreciated.
Thanks

Good morning everybody!
At the first boot, kudzu tell me that my mice must be eliminate.
In X my mice doesn't work. I chose a generic ps/2 with 2 button ( a
Logitech). During X's configuration my mouse was OK! I have the same problem
with Mandrake 8.0. The mouse's section in my XF86conf is...
##########################
Section "InputDevice"
Identifier "Mouse0"
Driver "mouse"
Option "Device" "/dev/mouse"
Option "Protocol" "PS/2"
Option "Emulate3Buttons" "on"
Option "ZAxisMapping" "4 5"
EndSection
############################
There is another file called XF86config.old. Its mouse related section is...
############################
Section "Pointer"
Protocol "PS/2"
Device "/dev/psaux"
#.....

Emulate3Buttons

##############################
I've already upgraded Xconfigurator and mouseconfig, but my mouse doesn't
work yet.
With MDK 7.0 I didn't had the same problem. Why?
What's happening?
Thank U

How about converting the mp3s with say xaudio or mpg123 or ...

If you _need_ it in one go, well why not write a small script?

I have also had this problem in Red Hat 7.1, not seen in earlier
releases. Either of at least two causes could be at fault:
1. The soundcard drivers camp on IRQ12, which is needed by the
mouse. "cat /proc/interrupts" can give a clue to this. Try
unloading (rmmod) the sound drivers and see if that helps
the mouse. Then if it works, and you want sound, you will
need to make those drivers use a different IRQ.
2. kudzu does something to disable the mouse. This happened to
me also. I verified it by booting in single-user mode and starting
gpm (the console mouse) which worked at that point. But, after
after running kudzu, the mouse was dead. If this is your problem,
then you must prevent kudzu from running at boot-up. Either
uninstall it, or disable the "S" links in /etc/rc.d/rc?.d.
Hope this helps, and happy Linux-ing.

Subject: help needed with segmentation faults with 3D
Date: Sat, 2 Jun 2001 13:33:28 -0000
I'm having a nightmare trying to get NVidia drivers working with XFree4.0.1.
I've managed to install the newest drivers available and Loki's test
software seems to agree with me. X starts with no errors and in fact
displays the NVidia picture briefly on start up but when ever I try to start
anything that enables 3D it invariably doesn't work.
The usual error that occurs is segmentation error and core dumped which
means absolutely nothing to me but hopefully might to someone a bit more
clued up! Some more commercial games such as the Sin demo run fine with
software render but lock up X as soon as you enable hardware render.
I'm running Mandrake7.2 on an AMD K6-2 with an NVidia TNT2 M64 32meg video
card and XFree86 4.0.1 with NVidia drivers ver 1.0-1251.
Thanks in advance for any help

Not for me it doesn't!
I try -X33 -X66 -X68 -d0 -d1 and each time /sbin/hdparm -i /dev/hda shows "*udma5"
The drive performance definately reflects each selected DMA mode.

since price is the deciding factor, the monitor, printer, and scanner don't
count. only plug the boxes nito the UPS, and plan to do an orderly shutdown
very soon after the UPS signals a power failure. Most of what you pay for in
an UPS is the battery, hence less capacity == cheaper.
> Does one need accompanying software to power the system down in linux?

the software should already be floating around your machine. typically, you
plug the signal cable into an unused serial port. the daemon watches one of
the handshake lines, and takes action when it goes high (or low). The HOWTO
is as complete now as it was in 1997.
There may be UPS's that provide a slicker interface by now; i'll defer to
someone else for that answer, but the basic functionality is pretty easy to
implement. you don't really need pie charts, graphs, statistics, and snappy
dialog from a UPS.

Good Morning,
I have a Tripp-Lite INternet Office 500. Tripp-Lite supports Linux, and
has a downloadable daemon, which supports network notifications, orderly
shutdown of the protected system. The only drawback to this unit is
that it's interface is relatively stupid. Contact closures only, not
statistics about the voltages, or battery condition. For the price it
works fine. I have the PC, monitor and cable modem on the UPS. The
rest of the system is on commercial power.
There is a generic daemon (upsd or powerd) that support many different
manufacturers and models. It was probably in your ditro.

mount the partition read-only to freeze the state during your
copy/dump. then use dump, tar, cpio or cp -ax depending on what you
want to do.

You have DMA set to on. Are you allowed to do that with your harddrive/ide

your motherboard.

My local computer store selection has been very slim and does not look

Hence, I have always done my component shopping online at stores like
buy.com or necx. The variety at buy.com seems to be shrinking, as its
prices increase, and necx was bought out by someone else. So, does
anyone know any reputable online vendors that don't over charge? If
they do recommendations for Linux supported hardware that would be
