Closed: eeepc patched kernel?

[jeff.sadowski]

Is there an eeepc specific kernel that has a patch to fix its wireless for powering it off and back on?

I realize now with kubuntu 9.04 I can turn off the wireless power with

ifconfig ra0 down
modprobe -r rt2860sta
echo 0 > /sys/class/rfkill/rfkill0/state

however it will not wake back up till I do

echo 1 > /sys/class/rfkill/rfkill0/state
modprobe rt2860sta
ifconfig ra0 up
SIOCSIFFLAGS: Operation not permitted
and reboot

I want to remove the error and reboot step

I just upgraded to the 2.6.28-13-generic kernel and modules

I have no error messages till I do
echo 1 > /sys/class/rfkill/rfkill0/state
modprobe rt2860sta

Then I get in dmesg

<-- RTMPAllocAdapterBlock, Status=0
rt2869 0000:01:00.0: setting latency timer to 64

ERROR!!! H2M_MAILBOX still hold by MCU. command fail

looking around on the net I found mention of patches and that it might be fixed in 2.6.29
is there an easy way to try 2.6.29 or find a package that has the patch applied already. A kernel that is specific for the eeepc

=============================================

I may have answered my own question I just found this

http://array.org/ubuntu/

I will follow the instructions on howto install it and get back to this thread

http://array.org/ubuntu/setup-jaunty.html

=============================================

update even with this kernel I still have the same issue

=============================================

success

After reading the forums at array.org I figured out that I needed to add

pciehp.pciehp_force=1

to my kernel line in grub and now It works with the following script

toggle()
{
 state=`cat /sys/class/rfkill/rfkill0/state`
 if [ "$state" = 0 ];then
    start
 else
    stop
 fi
}

start(){
 echo 1 > /sys/class/rfkill/rfkill0/state
}

stop(){
 ifconfig ra0 down
 modprobe -r rt2860sta
 echo 0 > /sys/class/rfkill/rfkill0/state
}

case "$1" in
start)
start
;;
stop)
stop
;;
toggle)
toggle
;;
esac

it was unnecessary to install the other kernel the generic kernel works fine as long as you add the grub option to the line.

I created a file that should automatically fix grubs menu.1st file when a new kernel is installed
the file name is /etc/kernel/postinst.d/eeepc_wireless_fix

#!/bin/bash
# look to see that pciehp.pciehp_force=1 option is added
# if not add it to a max of 10 lines
max=10
x=0
while [ $x -lt $max ];do
kernels=`grep -n ^kernel /boot/grub/menu.lst | grep /boot/vmlinuz`
wo=`echo -e "$kernels"|grep -v pciehp.pciehp_force=1`
if ! [ "$wo" = "" ];then
first=`echo -e "$wo"|head -n 1|cut -d: -f1`
lines=`wc -l /boot/grub/menu.lst|awk '{print $1}'`
let oneminus=$first-1
let amount2tail=$lines-$first
before=`head -n $oneminus /boot/grub/menu.lst`
after=`tail -n $amount2tail /boot/grub/menu.lst`
line=`echo -e "$wo"|head -n 1|cut -d: -f2`
line="$line pciehp.pciehp_force=1"
echo -e "${before}\n${line}\n${after}\n" > /boot/grub/menu.lst
else
break;
fi
let x=$x+1
done

make it executable and it should work
