After reboot: My patch runs just fine

On a side note: I've disabled preemtible kernel now and it really makes a difference on my system. Before it seemed rather sluggish when there was heavy hard-drive activity, sometimes even disallowing me too take any action, now my box seems to respond faster when wanting to do multi-tasking. I've read some other reports about slowness, so I thought I'd just mention it :)

Well I feel silly... that certainly explains why ALSA is telling me it can't find any soundcards, because 8820 is the only driver I attempted to compile in. Thanks for finding that out!

Here's hoping that the next love sources have a happy 88x0 driver! ;)

SOLUTION!

edit /usr/src/linux-2.6.4-rc2-love1/sound/pci/au88x0/au8820.c (or 8810,8830)
and add a line:

#include <linux/mod_devicetable.h>

I'm not quite sure *what* was broken... but this fixes it :)

EDIT: NO, it does _not_ work... more things have changed... and I don't seem to be able to repair it :(

EDIT2: finally compiled without unresolved symbols...

From Linus Torvalds <>
Subject Linux 2.6.4-rc3

Hmm. Nothing earth-shaking here, most of the changes end up being minor code cleanups and fixes for things like memory leaks in some error handling paths etc.

See the full log for more details.

I'm not familiar with creating patches, so there is the whole directory gzipped :)

Works on my AU8820, may crash yours :)

http://www.thinkgeek.cz/link/au88x0.tar.gz

EDIT: I forgot to mention that you need to compile intel8x0 and mpu401 in kernel in order to get it working, their components are required by au88x0 but are not listed as dependency, also see my previous post and modify the Makefile

the way i make patches is i have the base love-sources directory and then i make a copy of that directory where i make my changes, then when i'm done i go to /usr/src and run (using evil-sources as the obvious example)
Code:
diff -ruN linux-2.6.4_rc2-love1 linux-2.6.4_rc2-evil1 |bzip2 --best >2.6.4_rc2-evil1.patch.bz2
if you are not going to bzip the patch, you can get rid of the pipe to bzip2 and eliminate the bz2 extension from the end of the file name, the redirect is necessary because diff outputs to stdout

Hmm... well, I got the driver to compile, but no amount of screaming and yelling will make it work. I eventually started making everything as modules in hopes that would shed some light, but no luck. The modules seem to load fine at boot by /etc/init.d/alsasound start, but when I try to use alsamixer to unmute the card I get:
alsamixer: function snd_ctl_open failed for default: No such device

A pain to be so cluse, yet seemingly so far! I did compile mpu401 (which yes, was required), but I didn't notice a intel8x0 dependency - though it is there just in case.

Hi,

Just wanted to say that I was getting a kernel bug and segfault at fs/proc/generic.c (I don't have the exact error message right now). It was the emu10k1 driver bombing out. Removing the 'BUG_ON' line (as evermind suggested) from generic.c and recompiling fixed it. Can anyone comment on why that was a problem?

Thanks again steel for another great release!

O, I found out what causes higher idle temps for and already reported that to lkml: Using pm timer instead of tsc as time source causes this.

A first test result posted at lkml showed that a gcc compiled kernel was faster in 2/3 of all lmbench tests.

I doubt that the kernel does a lot of that kind of stuff where sse2 shines. But I am sure someone will do benchmarks and then we see. I at least won't use icc on my home systems, no matter how fast it is. Just a lisence thing. ;-)

i compiled the latest love-sources with icc a bit ago,
and apart from a bunch of warnings when compiling
relating to 'unknown' CFLAGS, it went well.

there's no difference in performance i can see though.
perhaps it's something only benchmarks can reveal.

or i just haven't found a good real-life method :wink:

*update*

when i ran updatedb, my system slowed down to a
crawl (using all ram and swap and cpu), and i was
forced to press the reset button, resulting in a forced
fsck during boot, which fixed quite a bit.

this has never happened before with gcc-compiled ker-
nels, so i am going to assume that icc messed something
up.

i'm back to good old gcc.

One post in the lkml thread I linked to above mentions the case of icc generating incorrect code without throwing an error. Perhaps this is a similar case.
I understand the kernel hackers do play quite a bit of tricks with the compiler, do they not?
