rt2500 driver PROBLEM - SMP kernel

hello,

EDIT
do any of you have a PKGBUILD for a kernel without SMP - or a package? i'm having troubel with compilation.

Hardware: Sitecom WL-115 pci sold in holland - http://www.sitecom.com/products_info.ph … 3&grp_id=6
Driver: RT2500 - http://rt2x00.serialmonkey.com

The issue is this:
1.) the computer boots perfectly
2.) network is activated with the ESSID
3.) network deamon works
4.) after 5 min. I lose connection to Access Point, connects to another Access Point (the wrong one)
5.) Immediately crashes


I have a wireless router at home of the same brand as the NIC. there are people with other AccessPoints somewhere around here because I detect 2 more. I can't connect to those obviously, and I dont want to anyway.

In gentoo and ubuntu, if my card lost the connection to the Access Point, i would have to go to the network settings and change the ESSID back to the correct one. That was it, it didn't crash or anything else. The driver was compiled in gentoo through portage, and in Ubuntu I compiled it myself and installed it myself. It is the same driver as the one I'm using in Arch Linux.

This is what I tried:
1.) Change mode to Ad-Hoc
2.) Forced to register to my AccessPoint with the 'ap' option in iwconfig
3.) restarted daemons
4.) dmesg says nothing

None of this helps.

UPDATE

i learned what the problem is, except i still need help.

I'm running Arch 0.7 . i haven't updated anything. i haven't done pacman -Su so everything on the system is still from the ISO image. however, i dont understand why the kernel that is installed with the iso intallation contains a SMP kernel! i dont have a SMP cpu.

because of conflicts with my wireless driver, i need to disable SMP in my kernel. how do i do that? if I update my kernel will it still be SMP? do i need to compile the kernel on my own?

i'm asking with without trying it because my computer is freezing since the NIC is connected.

Re: rt2500 driver PROBLEM - SMP kernel

The problem isn't so much SMP but preemption with rt2500. In order to disable both of these features you will need to compile your own kernel.

Re: rt2500 driver PROBLEM - SMP kernel

I have trouble with the rt2500 on arch too. (I know this is an old post btw).

The moment I use the iwconfig command, my whole system freezes. I just found this thread and am about to try and recompile my kernel, disabling preempting and smp. Still, I find that weird because neither my Ubuntu install, nor my Gentoo install suffers from the crashing problem. I'm sure at least the Gentoo install preempts too. Ubuntu probably as well.

Both are 64-bit installs though, maybe that matters. I'll report back (hope I remember) when I rebuild my kernel.

Re: rt2500 driver PROBLEM - SMP kernel

In post 2.6.13 the problem is only smp, preemption works fine with rt2500 (teh situation is different with rt2x00). Just recompile your kernel with smp disabled (I tested both with arch default 2.6kernel and with archck, which I run usually).

Re: rt2500 driver PROBLEM - SMP kernel

rt2500 is NOT compatible with SMP.

the ArchCK package i am releasing later this arvo to community will not have SMP.

Hopefully rt2x00 will stabilise... I want my smp back sad

Re: rt2500 driver PROBLEM - SMP kernel

Have you tried just passing "nosmp" from the bootloader  ???.
Let those that can't live with it turn it off, leave it in for everyone else.

Surely the rt users can't be that high a proportion of the user base.
I have a rt2400 based card that I haven't bothered configuring - might just do so for the educational value.

Re: rt2500 driver PROBLEM - SMP kernel

I got the Archck  kernal (which sounds really cool) and installed it just fine.
Then I went to the AUR and found this:
http://aur.archlinux.org/packages.php?d … s=0&SeB=nd
and tried to makepkg but it said:

rt2500.ko failed to build!
make: *** [module] Error 1
ERROR: Build Failed. Aborting...

Any ideas on what I'm doing wrong?
Thanks,
Wayne

That does not work. It is the SMP build that freezes rt2500. I use a custom kernel (one vanilla, one vanilla+suspend2) with Preemption, no rt2500 trouble here.

As for rt2x00, you can not expect it to finish for a long time, they started the third rewrite recently, and it probably won't be the last one due to the kernel wlan stack cofusion (ieee80211 vs. softmac vs. hostap vs. another one). The current rt2x00 rewrite is based on softmac, if that one doesn't go to the vanilla kernel, there will be another rewrite and it will take more time ...

Re: rt2500 driver PROBLEM - SMP kernel

I was wrong about one thing: I am now writing this posting while online with the rt2x00 driver. I can only test rt2500pci (which covers all rt2560 pci and pccard devices). The rt2560 devices work in open, wep and wpa (psk and eap) mode, I only tested wpa-psk myself.
I also read that rt2500usb doesn't work yet, I don't know if rt2400 or rt61 are ok.

I think I'll write a wiki page about the necessary steps to make the driver work, perhaps someone can test it with SMPkernel.

EDIT: Visit http://wiki.archlinux.org/index.php/Rt2x00 for further instructions
