I would like to know the answer to that as well. I have the same problem with
the 2.2.12-20 kernal. As far as I can tell, it is not possible to rebuild the
kernel with the AIC7xxxx drivers and actually get it to boot. I spent several
days fighting the "UNRESOLVED SYMBOLS" error on boot. So am I stuck running the
kernel that was installed from the RH installation CD. Like you, I also turned
on every damn scsi module there was and I even tossed in the IDE modules as
well. No luck. There is some magic trick that the installation CD knows about
that allows the aic7xxxx to run with the default install, but for whatever
reason doesn't work when regen'ing the kernel. I have to conclude there is an
error in the dependencies ("make dep") that is causing this. But I have no clue
how to track it down.

It depends on what depth you are prepared to look at. To look at the core
of the kernel you can post on newgroups with particular questions, look at
the source of the kernel or look at the linux-kernel archives for discussions
about the issues at hand.

Subject: ASM problem building kernel
Date: Wed, 13 Sep 2000 16:32:10 -0700
I am trying to build the 2.2.14 kernel with the one-line patch to enable
"proper" core dumping in multi threaded programs. I am getting assembler
errors however. As a background, I have built many kernels before, but
have not done too much kernel hacking.
I'm trying to build the 2.2.14 kernel that came right off the RedHat 6.2
CDROM and using gcc 2.95.2. The error is nowhere near the single file I
altered. It must be something with my compiler, since a colleague built
it fine with egcs 2.91.?.
Here's one error:
make[1]: Entering directory `/usr/src/linux-2.2.14/arch/i386/kernel'
gcc -D__KERNEL__ -I/usr/src/linux-2.2.14/include -Wall
-Wstrict-prototypes -O2 -
fomit-frame-pointer -fno-strict-aliasing -D__SMP__ -pipe

{standard input}:1253: Error: no such 386 instruction: `movups'
{standard input}:1254: Error: no such 386 instruction: `movups'
As far as I can tell, this is happening only in three functions in this
file:
copy_thread, dump_fpu, and __switch_to.
The assembly output looks like this in each case:
#APP
movups %xmm0, 0x00(%eax)
movups %xmm1, 0x10(%eax)
movups %xmm2, 0x20(%eax)
movups %xmm3, 0x30(%eax)
#NO_APP
The C code responsible is the macro unlazy_fpu() in each function, which
in turn calls another macro save_kern_fpu. However, my ASM is a bit
rusty, but I imagine movups is an instruction to save MMX registers.
I tried playing with setting optimization to PIII, i586, etc... to no
avail.
My assembler has version:
% as -v
GNU assembler version 2.9.1 (i686-pc-linux-gnu), using BFD version 2.9.1
Any help is appreciated.

Hmm, I had no difficulty bulding the AIC7xxx modules in and having it work,
for 2.2.x with x = 12, 13, 14, 15, 16, 17
and for
2.4.0-test-y with y=7 and 8.
Note that I built IN the modules, I didn't try to load them.
I have a comment or two on your problem with 2.2.x below:

I think the problem might be that you compiled a new kernel with AIC7xxxx
AND you're trying to load in a module with AIC7xxx. Check your init
scripts and see if they're forcing a load of AIC7xxx.
A second thing to check is to make sure that you're loading the RIGHT
AIC7xxx module. One compiled for a different kernel than one you're trying
to boot is likely to hoze you.

Several have done so; none that represent _realistic_ alternatives,

It seems to me that the "fact that X uses sockets" represents one of
those "unexamined fallacies" of life. Because it is a _false_
statement.
A modicum of research would show that it supports other transport
layers as well, notably local connections via STREAMS pipes and Unix
Domain Sockets, which are both Rather Faster Than BSD Sockets.

The problem is that in order to construct that "faster, more efficient
windowing system," you have to pick some set of functionality to give
up on. And the set of functionality _you_ are willing to give up
isn't necessarily compatible with the set of functionality _I_ am
willing to eschew, is not necessarily the same as someone else's
needs.
Furthermore, _much_ of the criticism that heads out against X11
reflects the impressions that some people have about what others have
written about their prejudices, as opposed to representing actual
criticism of X11 itself.
See <http://reality.sgi.com/opengl/d11/d11.html> on SGI's
X11-compatible system that examines the notion of having special
transports available for local applications.

I presume that you have a graphics card with 32MB of memory? Keep in
mind that _that_ memory gets counted as part of X's "footprint," in
addition to whatever memory is used in "user space."
I would find it unremarkable if someone running a 64MB graphics card
would find that they were using over 100MB of RAM...

Hi,
How do you use a member function as the start routine
to pthread_create? Pthread_create takes a
void * (*)(void *) parameter, but a member func. is
void * (Class::*)(void *)
I'm tried pthread_create(..., &start_routine, ...),
but am getting warnings about the casting above.
TIA.

the clock on the UART is 115200. you can have any divisor of this.
as it happens, 8*14400 = 115200. you are in luck.

setserial. set the divisor to 8.

Any casting is wrong. Pthread create wants a plain C function; you must
write a function
extern "C" void *thread_func(void *) { /*...*/ }
Passing a pointer to a C++ object through the argument parameter and invoking a
method I leave as an exercise to you.
Under most compilers, you can also get away with using a static class member
function, or an ordinary non-member C++ function when a C library wants a
function pointer, though this is non-standard usage.

(The assembler is not the compiler.) Perhaps you should try a newer
binutils, with a version number like 2.9.5.0.16 or 2.10.0.24 or some
such.

I don't understand this thread. We've been using scisi drives with
that module since 2.0.XX kernels. They are modules for the
generic kernel. Of course you have to have an appropriate entry
in /etc/conf.modules, and in order to boot you need an initrd
statement (and you must have run mkinitrd). Way back under
RH4.2, we went to the trouble of making kernels with SCSI
support built in but we haven't bothered doing that since
RH5.X.

The following is the listing of my lilo.conf:
#boot = /dev/ide/host0/bus0/target0/lun0/disc
boot = /dev/scsi/host0/bus0/target0/lun0/part1
#boot = /dev/sda1
disk = /dev/scsi/host0/bus0/target0/lun0/disc
#disk = /dev/sda
bios = 0x80
disk = /dev/ide/host0/bus0/target0/lun0/disc
# bios = 0x80
# sectors = 63
# heads = 255
# cylinders = 2495
lba32
map = /boot/map
install = /boot/boot.b
prompt
image = /boot/vmlinuz-2.4.0-test5
label = linux
root = /dev/scsi/host0/bus0/target0/lun0/part1
# root = /dev/sda1
read-only
append = "video=aty128fb:1280x1024-32@75"
other = /dev/ide/host0/bus0/target0/lun0/part1

other = /dev/scsi/host0/bus0/target0/lun0/part3
label = win98

I am using linux kernel 2.4.0-test5, with devfs option. That is why the
/dev hierarchy is so deep. The commented lines are either for backward
compatibility or are unsuccessful installations. I'm still not having any luck
installing lilo onto the ide hard drive. It stops, both with the
geometry setting and without, at LI. I have also tried to give lilo the
"normal" geometry of the drive. All to no avail.
