At a guess...
Are you using the standard kernel serial driver from v2.2.10? If so then
the serial driver you're using doesn't properly support PCI.
So, although you can spot it resources etc. and use setserial to get at
it, and although if you do this it'll work, the driver itself won't
cope with IRQ sharing!
The solution is to use the latest version of the serial driver
that is being developed, from serial.sourceforge.net (IIRC),
and see how you get on with that. I'm using that (with a few hacks)
to use a dual serial card I've got and am happily sharing it
with other IRQs -- I had exactly the same problem as you're
having before using this as I similarly got the same error
(and guessed the cause.)

Subject: upgrading to glibc-2.2-9 causes problems
From: [EMAIL PROTECTED] (Victor S. Miller)
Date: Tue, 02 Jan 2001 01:56:37 GMT
I'm running RH7.0 on a Pentium MMX 166Mhz, 32MB memory. I just upgraded
(did a rpm --freshen) on glibc-2.2-9. I previously had
glibc-2.1.94-3. However after doing this, I suddenly start getting
messages like the following one when I load xmms:
undefined symbol: __getfpucw
(this isn't the only program that gets it. I even tried uninstall
xmms, and reinstall it -- I still get the same message, xmms is
version 1.2.4-1). Now, I'd like to revert to the old version of glibc
-- but so many other packages depend on it, that I can't unistall it.
I tried doing rpm --freshen --oldpackage with the 2.1.94-3 rpm, but
that seemed to do nothing at all. Can anyone suggest how I can fix
things?

I have a new Toshiba Satellite 2805-S201 that comes with Win ME and I
really want to switch it over to Linux.
Can anyone tell me if they have done it successfully and which
distribution they used. I need to be able to use the USB, LAN
connection, modem and the DVD player.
Also this might be a stupid question, but you can watch DVD movies
under Linux, correct?
I know you can hotsync Palm Pilots, but what about the possibility of
linking a Casio Q3000EX digital camera, RIO 500 MP3 player and Sony
miidisc player/recorder :)
Thanks for any help.

Yup. That is the way it is with Linux. Many of those are configuration

Sorry. To do so you have to include all programs and all libraries he

Subject: Running Linux in RAM
Date: Tue, 02 Jan 2001 02:04:01 GMT
I have a Linux machine in an industrial setting. The machine needs to
be able to withstand any type of power interruption by rebooting itself
without any user interaction.
I checked out ReiserFS, but it seems that it still might require some
intervention, and it's really not the right solution to my problem.
I really want to run all of the kernel bits in RAM, and have the HDD
mounted read only for all of the support software. The computer does
not need to save any information permanently to the hard disk. It just
needs to support multiuser mode.
Is there some way to make an image, copy it to ramdisk, then launch
from ramdisk?

Subject: Opti931 DMA 0 problem
Date: Tue, 02 Jan 2001 03:00:02 GMT
I'm using an older ISAPNP soundcard based on the opti931 chipset.
When trying to use it in linux 2.2.18 with the built in mad16 driver
in full duplex mode, the channel using DMA 0 gets IRQ timeouts.
kernel: Sound: DMA (output) timed out - IRQ/DRQ config error?
I've tried this card in two different motherboards, the A-bit KT7-RAID,
and now the EPOX EP-8KTA2. Both of these only have 1 ISA slot, and both
had the exact same DMA 0 problem. I also tried an AWE64 board, and
dma0 channel 0 wouldn't work either. In the BIOS nothing seems to be
using DMA 0, and I've even marked it as LEGACY/ISA on both motherboards
with no benefit.
Does anyone have any clue as to why DMA 0 isn't working?
I've looked at the OPTI931 data sheet, and evidently full duplex mode
works with pairs of dma channels, like this:
INPUT DMA OUTPUT DMA
0 1
1 0
3 0
Since dma channel 0 is required for each case, I can't get full duplex
to work. Either input works and output doesn't (irq timeouts), or
output works and input doesn't (same irq timeouts). The mad16 driver
seems to be aware of these 3 combinations for dma and dma16, so it
will try to set the board up correctly and warn you if the dma
channels selected aren't supported. For example DMA 1 and DMA 3 are
not allowed.
But wait! I've tried windows, and looking at their resource allocation
for the board they are using DMA 3 and DMA 1, which the data sheet
doesn't seem to allow for full duplex. And with that setting, I can
be recording from the microphone while playing a sound sample--ie
full duplex is working.
I was messing around with the mad16 source trying to get it to work,
and somehow using DMA 1 and DMA 3 I was able to get the driver working
in full duplex, but just once, and I can't reproduce the result. My
/etc/isapnp.conf is set up correctly, the /etc/conf.modules matches,
I'm doing everything correct, but for some reason whatever is using
DMA 0 doesn't work. And I can't figure out how windows was able to get
full duplex using DMA 3 and DMA 1.
To me this is a baffling problem. It is not the sound card that is bad,
because I've tried two soundcards and dma 0 doesn't work for either.
It's not the motherboard that is bad because I've tried two (actually
3) motherboards. I don't know why I haven't seen posts related to
this problem, because it appears that with these newer motherboards
everyone trying to use dma 0 in the ISA slot will have trouble.
Another question I have: The motherboard has AC97 sound built in, and
I've gotten that to work using the ALSA snd-card-via686a module.
It works fine, but there are irritating clicks when the /dev/dsp is
opened or closed, and I can hear the PC speaker blasted out through
the stereo when the machine is powered up. The problem with using the
AC97 onboard sound is that the microphone input level is too low. The
OPTI card has an option under windows to add 20DB amplification on the
input, I'm wondering if that is a standard ability on sound cards and
whether the VIA686A driver just forgot to flip the switch? I haven't
been able to find any technical docs on the VIA686 chip to know whether
that 20 DB amplifier might be present and how I can modify the driver
to turn it on...
My cpu is a 1 gig Athlon Thunderbird. I'm running linux 2.2.18.
Any ideas appreciated, but please post your replies because I don't
check this email address.

It is no big deal for a user to see most of these files except for maybe
say.. /etc/login.defs which is where you can change the minimum allowed
length of passwords for the users and root. So it is one I change so
that a user doesn't know that my root password is not set to the same
length as a user's. There are a couple of others I block access to.
If you don't want a user to be able to read some of the files in /etc
then don't allow access to some of these files if their original
permissions are 644 and owned by "root.root" If any of the files are
owned by "root.program" it may cause problems with the program.
chmod 600 /etc/filename
You can keep users out of the init.d scripts with this.
chmod -R 700 /etc/rc.d/init.d/*
This will stop user access to all of the files in /etc/rc.d/init.d/ and
since the files in /etc/rc.d/rcX.d (X= 0-6) are symlinks it blocks them
from user access also.
