There's a few who distribute linux, like Red Hat, Debian, Slackware,
Caldera, S.u.S.E ..
I guess it's that's what you're looking for.

Subject: msdos module broken under 2.2.6
Date: Sun, 18 Apr 1999 15:11:40 GMT
I just upgraded from 2.2.5 to 2.2.6 on a 586 (using egcs 1.1.1). I
made no configuration changes, did a make dep ; make clean ; make
bzImage ; make modules ; make modules_install. Everything went
smoothly and the new kernel boots. However, I cannot mount my dos
partition.
Here's what happens when I try and load the msdos module manually
modprobe -v msdos
/sbin/insmod /lib/modules/2.2.6/fs/fat.o
/sbin/insmod /lib/modules/2.2.6/fs/msdos.o
/lib/modules/2.2.6/fs/msdos.o: unresolved symbol is_binary
I grepped the fs sources and indeed there is an is_binary routine in
fs/fat/misc.c (which is compiled); moreover nm fat.o | grep is_binary
shows:
00003df0 T is_binary
Any ideas?

I'll gladly give more info if I knew what else to give. I was running the

System summary:

Going back to 2.2.5... I'll let everyone know if I see somthing similar.

possibly 'fbset' can help you, so you can disable fb while using

Subject: HELP!: thread cannot see child, forked before pthread_create
Date: Mon, 19 Apr 1999 09:03:23 +1000
Hi
I am in the middle of rather a large project at Uni but I have a problem
with my gcc or maybe linux 2.0.34
i link with gcc -D_REENTRAN -lpthread
The problem is that:
I fork a child and exec a prog
I then communicate via two pipes
I create a thread to watch for output from the process until the pipe is
closed at the child end.
Well when I do a wait on the child from within the thread the wait
returns -1.
with errno set to ECHILD
Now after hours of stress I uploaded all the code to one of the universities
computers and it worked perfectly.
Anyone know if there is any other linker switch I must activate?
Cheers
Peter

I'm using SuSE 5.3 linux. Recently, i'd compiled MySQL 2.21.33b and many
other software package(using GCC). The problem is that when compiling,
the error called "Segment Fault" often caused. I've no idea about this
error. Is that a bug? or that's my mistake setting up the wrong compiler
options. But also had tried compile the same programs on Slackware
linux, there was no problem.
Could anyone help me clarify this problem?
Thanks in advance

get the current dhcpcd. i am using version 1.3.17-pl3.
you'll need to modify some scripts slightly since the new version has
a better syntax and mode of operation.

Reply-To: [EMAIL PROTECTED]
I believe the following should work: (at least close to the general idea....)
1. read the base address register from the PCI Config (this is the physical addr)
2. use 'kmalloc' with 'GFP_KERNEL' priority to allocate memory on the kernel space
ex: kmalloc( xxxxx, GFP_KERNEL); refer to a linux kernel book for the
right syntax
3. Remap the PCI memory using either ioremap or vremap (depending on the kernel
version you are using)
ioremap ( xxxxx, size of registers) ; <-- refer to a Linux kernel book
The remap page is the virtual address.
This will map it to kernel space. I believe you will have to copy the data from
kernel to user space later. There is a few (that I could find) PCI I/O mapped
examples on the web... surf the web...
sorry, I did not bookmark the links...
Good Luck,
Jeff-

Hi, my Linux LAN to ISP router died today unexpectedly. It seems the LAN card
(A generic VIA-RHINE based card) barfed. Here's what showed up in kern.log
Apr 18 10:47:45 Heavy2 kernel: eth0: Something Wicked happened! 0009.
Apr 18 15:57:45 Heavy2 kernel: eth0: Something Wicked happened! 0009.

Apr 18 23:34:02 Heavy2 kernel: eth0: Something Wicked happened! 0009.
Here's what syslog shows when the via-rhine.o module is loaded at bootup:
kernel: via-rhine.c:v1.00 9/5/98 Written by Donald
Becker

Setting to 64 clocks.
System is a Cyrix P150+, 24 megs RAM, SiS 5571 chipset based MTech
motherboard, internal US Robotics modem, internal S3 Virge video card,
misc other stuff. Prior to this I was running an original DEC produced card
with the 21041 chipset. I replaced it with the Rhine card in the hopes of
getting a 10/100 hub in the future.
What's up here? What does it mean when "Something Wicked happened!" ??

Right. Richard Gooch doesn't have this in his Kernel Newsflash page
yet (http://www.atnf.csiro.au/~rgooch/linux/docs/kernel-newsflash.html)
but I imagine he will soon. Browsing through patch-2.2.6.gz, looks
like:
- a lot of material was removed from include/net/irda/irmod.h
including `#define CS_ASCII 0x00'
- `#include <linux/irda.h>' was added to five or six files
- include/linux/irda.h did not and still does not exist
Draw your own conclusions. You might try creating a dummy
include/linux/irda.h with `#define CS_ASCII 0x00'. Dunno if that would
work or not, haven't tried it. Alternatively, roll back the irda
updates in 2.2.6.
