Post subject: 2.6.37-0.slh.15 + rt3090 wifi: still freezes the shutdown  PostPosted: 01.02.2011, 20:59

since I wrote about this issue
http://www.aptosid.com/index.php?name=P ... highlight=
time to time I tried new kernels
no one solved the issue, the system freeze at shutdown persists
I'm still forced to use the kernel 2.6.33-1.slh.5, the latest I have that does not cause issues with rt3090

Hi pinguin,

I recently managed to solve the same problem in my netbook with kubuntu 10.10 (link), could you try it and tell me if it works? I'd love to come back to aptosid if it works, but I have no time right now to try it Confused

Basically what I did is blacklisting: rt2800pci, rt2800lib, rt2x00pci, rt2x00lib, rt2x00usb and loading rt2860sta

Hope it works for you too.

Fran

Of course,

first, add this lines in "/etc/modprobe.d/blacklist.conf"

      Code:
blacklist rt2800pci
blacklist rt2800lib
blacklist rt2x00pci
blacklist rt2x00lib
blacklist rt2x00usb


and then, add "rt2860sta" to "/etc/modules"

I have just tried it in a live session and the module rt2860sta was not found, so it won't probably work Sad

I *think* it needs the package "firmware-ralink":

      Code:

root@debian[/home/finotti]# apt-cache search rt2860sta
firmware-ralink - Binary firmware for Ralink wireless cards

Well, I've been trying to make it work this afternoon and it has been impossible.Of course the package "firmware-ralink" it's necessary, but the problem is that aptosid's kernel doesn't have the rt2860sta module, so we can't use it.

I've tried compiling it by myself with no luck yet Sad

franute, I can confirm that your workaround doesn't work with aptosid kernel, probably due to slh assertion, that you can see in the post pointed by muchan

Thanks a lot pinguin and muchan for the information. Then I would probably keep the Kubuntu 10.10 instalation and wait until the rt2860 module goes stable or something like that.

Sorry that my fix didn't work Sad

I've been thinking, have you tried an aggressive solution? For example, killing the kernel modules before restarting or shuting down?

For example, create a file called remove-rt in /etc/init.d with:

      Code:
#!/bin/sh
rmmod rt2800pci
rmmod rt2800lib
rmmod rt2x00pci
rmmod rt2x00usb
rmmod rt2x00lib


change the permissions (chmod a+x remove-rt) and then link it to rc0.d (power off) and rc6.d (reboot):

      Code:
ln -s /etc/init.d/remove-rt /etc/rc0.d/K01remove-rt
ln -s /etc/init.d/remove-rt /etc/rc0.d/K01remove-rt


Of course everything as root and having firmware-ralink installed.


PS: it all might be a nonsense, but if the problem is caused by the modules, maybe removing them could help. Don't know... Question

This is going insane, rt2860sta/ rt2870sta are not leading anywhere.

@ slh, but, today, even rt2800pci doesn't look like a good module, as it leads to a system freeze at shutdown; it needs further develop to became stable; do you know if there are some people working to solve the issue?
@ franute in the meantime, I will give a try to your other workaround
