Subject: Kernel 2.4.0-test6 Compile and install module problem?
Date: Tue, 15 Aug 2000 02:41:01 -0500
I have been testign all the kernels thus far with most pretty much the same
configuration on the same PC laptop Dell Inspirion 7500.
If I configure the Kernel to include "umsdos" I get a binry error at the end
of the compilation and it bombs out. If I don't include "umsdos" the kernel
does succesfully compile but when I install the modules which is just PCMCAI
and SCSI, the SCSI module bombs out and I get a bunch of depmods at the end?
The scsi module folder thus is not created.
Now I say again this has not happend on any of the test hkernels thus far
except 2.4.0-test6. I am runnign Red hat. Right now I am running
2.4.0-test5. And yes I compile new kernels generally under the originally
instaled kernel that installs with Read HAt Linux 6.2 which I believe is
2.2.14-5.0.
Could there be soem scripting errors in thsi particular Source of test6???
Anyone see this happen to them??

What sound card do you have, and do you load it as module?
Do you initialise your soundcard under dos, and loadlin then into linux?
(Irq 10 is often used for the MPU401 compability of a soundcard)

Subject: Remote Boot Pxe toolkit
Date: Tue, 15 Aug 2000 09:54:23 +0100
Hi
I'm currently trying to configure remote boot, using the bootix pxe toolkit.
How do i need to configure the dhcp server so that it tells the client to
use tftp to download the file i have specified;
My dhcp server conf for the client reads;
option dhcp-class-identifier "PXEClient"
option vendor-encapsulated-options ff;
host pxeclient {
hardware ethernet 00:D0:09:53:BA:5D;
filename "pxboot";
fixed-address 192.168.57.200;
The file pxboot resides in the tftpboot directory and my mtftp.conf has the
entry
pxboot 192.168.57.200
Are these settings correct?
Any help would be appreciated?

Date: Tue, 15 Aug 2000 11:08:42 +0200
Hi,
I want to use the USB interface under SuSE LINUX 6.4 to control my own
interface board. The problem is, that the USB driver on host side only
transfers one packet per frame. I need a higher transfer rate of short
packages, which is allowed if bulk-transfer is used. Are there new USB
driver available or other solutions for this problem known.

And if we're going to have such a lousy implementation of POSIX
threads, then why implement it at all.
Yes, it would satisfy a few trivial programs. But real programs don't
just do getpid() for the fun of it, they usually do it so they can
pass the pid to a syscall, or pass the pid to another program which
may pass it to a syscall. And not all of those syscalls will
currently do the POSIXly correct thing (perhaps most importantly
kill(), but many others too).
The solution you suggest might give the impression that LinuxThreads
was nearer to POSIX compliance, when in fact it would just expose many
more subtle areas of non-compliance. If this getpid() implementation
was added as part of a concerted effort to develop a high-quality
fully compliant POSIX threads implementation, then great, but
otherwise I have difficulty seeing the point.

shows that with link LED, but how

Subject: Recovering from Segmentation Fault on driver load
Date: Tue, 15 Aug 2000 18:31:55 GMT
Okay, I know, "Don't do that!" Sure, but if every driver I wrote worked the
first time I insmod-ed it, I'd have to change my name to G-d.
So, I do an insmod and this driver produces a segmentation fault, say
because some subscript is 89 gazillion instead of 3, and it seems stuck
there. I can't rmmod to remove it.
Do I really have to reboot, or is there some other way to force the kernel
to unload an uninitialized module?
Thanks

Subject: Submillisecond timing
Date: Tue, 15 Aug 2000 20:29:45 GMT
Hi!
I need to develop an application which core is to write a voltage to an
external instrument wait a little bit and read a value from another
instrument. This is nothing difficult in itself but the thing is that the
whole thing must last 40 microseconds and that I want the error on that
time to be less than 10%.
What are the timing possibility in C++?
I am using Visual C++ 6.0 and the only information I found refers to timer
with a resolution of 50 milliseconds. Is there anything better than that?
I am currently under windows and some preliminary tests have shown me that
timing is in fact very unstable. I believe this is due to interupts from
windows. Can Linux help me in that particular instance for example by
putting a higher priority on my program over system tasks?
Thank you. Please answer at [EMAIL PROTECTED]

subsecond meaning microsecond.

Subject: Problems with libstdc++
Date: 15 Aug 2000 20:45:50 GMT
Hello,
I've been struggling with a problem in the standard C++ libraries. My code which
is heavily dependent on STL {vector,string} classes messes up when compiled and
run on a Mandrake Linux [Linux milestone.sonic.com 2.2.13-7mdksmp #1 SMP Wed Sep
15 16:38:50 CEST 1999 i686 unknown] machine. This code, when compiled and run on
both a SGI Octane running IRIX 6.5 and a machine running WinNT, runs perfectly.
The problem I am seeing relates to when a string grows larger than 36 characters
{I don't know where that magic # comes from}. But if a string I read from a file
is longer than 36 characters, mysteriously some of the values in a vector stored
in a totally unrelated object get thrashed.
Has anyone seen this problem? What is the work-around. As I said, the code looks
solid {And runs solid on any machine not running Linux}. If anyone is interested
I will send them the source to the project and let them kick the problem around.
For reference:
libstdc++-2.9.0-30
glibc-2.1.3-15
pgcc-1.1.3-3mdk

Subject: Kernel 2.4.0-test6!!!!! Anyone have any Problems?
Date: 15 Aug 2000 22:06:13 GMT
I am using Red Hat Distribution Version 6.2.
I noticed that my modutil needed updating as well as pcmcia-cs. That still
does not resolve the errors I get after configuring the Kernel for 'umsdos'
support. I get a binary output error at the end of the compilation. If I
remove 'umsdos' and re-compile the kernel it successfully compiles but there
is a problem with the module_install step. I get a bunch of depmods at the
end and it bombs out.
So far I have not had any problems with any of the test kernels until this
one.
I am using a Dell Inspirion Model 7500. It only takes 5 minutes now for me
to compile a kernel on my 750 mgh PIII. On my 233mmmx intel it took almost
30 minutes to complile these test kernels. what a huge difference in
time.:):):):)
