lsmod from both kernels I suppose.

dieghen89 · 2011-07-02 06:09:38

Yes, i know....it's the same with my optimus 2x
I should search something, but till monday i'm off, still have exams...

I'm missing the precompiled 2.6.39-3 on the Google code page. But I'll get it from the Dropbox repo instead:
[dieghen89]
Server = http://dl.dropbox.com/u/794061/arch/

I'm a long time user by now, and very happy about this kernel! Thanks for keeping up the good work

chemicalfan · 2011-07-13 09:44:24

Dieghen - can I make a request please? I've recently bought a USB wireless N adaptor (because, the wireless adaptor in my Acer Aspire One is a pile of crap, or the drivers are, I don't know, but it disables itself all the time). The driver isn't in your kernel, and I've looked through the config but I can't see it (I'm not pro kernel hacker though!). HOWEVER - it does work using the stock Arch kernel (I think I'm on 2.6.38 - can't remember right now, and I'm at work). Could you possibly find the differences, and include it in your kernel please?

It's a Realtek RTL8188SU chipset, I can post lsusb later if that'll help....

Zom · 2011-07-13 09:51:21

You could rather plug it in while you use the regular kernel and post "lsmod", that'll let us see what modules are loaded and go from there.

chemicalfan · 2011-07-13 12:15:33

Cool, I'll do that when I get in tonight

chemicalfan · 2011-07-14 01:41:29

Ok, that's weird, it doesn't work now! On first boot with the stock kernel (2.6.37), the lights flashed on the device, which has never happened before. I was trying to debug X at the time, so didn't look at connectivity.

Maybe it was doing some kind of hardware poll, as it was the first time I'd booted into the stock kernel since plugging the USB wireless device in?

dieghen89 · 2011-07-18 14:01:59

Next release i've done an heavy diet for the kernel

@knedlyk
I've also fixed the android internal memory problem

@chemicalfan
have you managed to get the usb wiki working?

chemicalfan · 2011-07-19 09:16:51

Nice one on the trim

I didn't get the wifi working I don't know what the flashes were when I booted the stock kernel, but it hasn't done it since. I don't know how to proceed, as I can't get hold of the driver from Realtek's website, and neither stock nor netbook kernel plays ball out of the box...

Zom · 2011-07-19 10:20:20

What kind of trim is it? I'd be interested in reading a changelog when you release the new version.

dieghen89 · 2011-07-19 18:42:25

Guys, i have wrote heavy but i want say the opposite...What does came in my mind that let me think that heavy means slight? Excuse me, my fault What a sorry figure....

The numbers of modules are a lot but the result is about 200kB less in the xz

@chemicalfan
mmh i haven't understood your full situation...Have you already tryed to open a new discussion?

chemicalfan · 2011-07-20 08:31:13

I haven't I'll admit - I thought it was a problem with this custom kernel, but as it also appears in the stock kernel, I think I'll raise a new post in that forum (even though they'll probably just send me upstream...)

ngsa · 2011-07-20 23:53:21

First, thanks for such a great kernel package. I have been a happy customer for a few months. I had not updated the package in a while. Today when I did, I was unable to rebuild an initrd image properly. I am using a LUKS setup (LVM on an encrypted partition). This requires a few modules to be available during boot.

When I rebuild a new initrd, I get the following output. I made sure LVM and encrypted partitions where enabled when kconfig came up. Is there anything else I could try? I am sure it is an oversight on my part. The current 2.6.39 stock kernel works fine. Thanks for any help.

dieghen89 · 2011-07-21 12:49:11

@ngsa
The sd_mod error i think it is caused by the BLK_DEV_SD (scsi support) is =y and not =m...If you don't use initrd you must have =y, and so it is useless add it into the initrd image when is already present in the kernel...So i suppose is a harmless error

Fot the others, could you try this?

ngsa · 2011-07-21 14:29:03

@dieghen89 thanks for your help. While running the stock kernel and downloading your new build, I issued the following commands which resulted in the same output as before (in previous post). Perhaps I am missing a step?

sudo pacman -U kernel-netbook-2.6.39.3-5-i686.pkg.tar.xz
sudo rm /boot/kernel-netbook.img
sudo depmod 2.6.39-netbook
sudo mkinitcpio -p kernel-netbook

chemicalfan · 2011-07-21 21:24:12

Sorry to interrupt, but my issue has evolved slightly. I've obtained the driver from the Realtek website, but it won't compile because "smp_lock.h" is missing from the headers of the netbook kernel source. Now, is this because I'm using the BFS patch? Could I just copy in the file from my stock kernel (2.6.37 though)

Edit: I've discovered that this driver is actually in the kernel under staging - it just isn't enabled under the default config for kernel-netbook... I'm going to recompile tonight once I've enabled it in the config - any chance you can make this permenant please?

I can use my Soundcard with default kernel using:

alex@tiny-escaped ~$ cat /etc/modprobe.d/alsa-base.conf 
options snd-hda-intel model=ref

Since the hda-intel module is build-in i tried the following after some research without success:

alex@tiny-escaped ~$ cat /boot/grub/menu.lst 
# Config file for GRUB - The GNU GRand Unified Bootloader
# /boot/grub/menu.lst

# (0) Arch Linux

Any suggestions?

I can't see anything odd there, are you sure ALSA is working correctly?

I think so, since the default kernel works flawless.

As i can see that i get different models even if i added snd-hda-intel.model=ref to the kernel line:
default kernel (working)

cat /proc/asound/card0/codec#0 | grep Codec
Codec: IDT 92HD88B1

netbook kernel

cat /proc/asound/card0/codec#0 | grep Codec
Codec: IDT ID 7667

EDIT:
oh.. i guess the driver is missing. lets see... recompiling now...

EDIT2:
yep. needed to add: CONFIG_SND_HDA_CODEC_SIGMATEL=y

Is there any news on the BFS patch for kernel-v3? I guess that's the main stumbling block for this project?

We are all waiting Con...Just now i'm preparing a kernel-netbook release without BFS
