Problem fixed.

Found something in the make output:

em8300_eeprom.c:44:2: warning: #warning Full hardware detection (and autoconfiguration) will be impossible.

Should I reconfigure my kernel?

Here we are. Does not works well.

em8300-0.16.2 makes system unusable if Kernel has no CRYPTO_MD5

Hi!

It really took a lot of time for me to figure out why em8300-0.16.2
broke my system, until I realized that missing CRYPTO_MD5 from kernel
makes the module go crazy with udev. Configurin CRYPTO_MD5 as a module
solves this.

This is what happens on my Gentoo:

- If compiling and loading modules without a reboot, no /dev/em8300*
is ever created. /sys/class/em8300 remains empty. Modules load without
any errors (no parameters), although there is a load of system
messages broadcast to every console when doing 'modprobe em8300'.
- If I reboot, udev freaks out around 'modprobe em8300', my root
remains RO, and all other kinds of nasty stuff happens. My init
scripts apparently hang. I could do a sysrq+killall, remount root RW
and fix everything at that point to get into a sane environment at
next reboot.

Juts a notice for everyone, hopefully this'll save someones time.
(maybe already fixed in CVS? If not, well then...). I did notice from
the archives of this mailing list there were some problems in regards
of CRYPTO_MD5, but it wasn't apparent for me that 0.16.2 breaks a
system so severely without it.

em8300-16.1 and below work correctly.

Also, this could have something to do with Gentoos patched sources
(I've used gentoo-sources ebuilds to install kernels, no vanilla),
though I doubt it.

Control by registers

Hello,
my name is Thomas, I am a student from Poland. I use two cards
to make my measurement site. I have to make software for synchronic
start of playing DVD disc's on two PC's. I will be using LabView to
make this software. I want to make this by control registers of DxR3.
I found on Yours website some tips and log from start up of the
Creative Dvd player. I have to find some procedure(sequence of sending
commands) to start playing MPEG2 Stream(from DVD-Drive) by using my
Dxr3 Card(I need have signal in TV-Out output) . Should I use all this
“reads and writes” to start sending MPEG2 Stream from DVD-Drive to
TV-Out of Dxr3 or I need only small part of this? Can You help me some
in this part of my research? Have You maybe some tips for my? Thanks
for help. Bye

P. S. Sorry for my English, I know it’s bad ?

Compile Error under Gen2VDR 1.2

Hello,
I've tried to compile the 0.16.2 under Gen2VDR 1.2 but it has failed with 
the following error message:

With release 0.16.1 compiling works fine. What's wrong here?

I have no idea what Gen2VDR is, but it looks like you aree trying to 
build the modules against an outdated em8300.h headers file...

Cheers,

Nicolas

Re: Compile Error under Gen2VDR 1.2

Hi,
Gen2VDR is a special version of Gentoo with VDR included. How can I update 
the headers file? Isn't it included in the modules-source? Or do I have to 
upgrade to a newer kernel?

Thanks!
Oliver

Find it and replace it with the include/linux/em8300.h file from the 
em8300 distribution.

> Isn't it included in the modules-source?

It is, but for some reason it is either outdated or overridden by an 
older one somewher.

> Or do I have to upgrade to a newer kernel?

No.

You may try to issue "grep em8300.h .em8300_main.o.cmd" in your 
em8300/modules dir to see what em8300.h is being used. And then either 
nuke it or replace it.

HTH,

Nicolas
