acer 4100lmi wireless kill switch problem

sohio · 11-24-2005, 06:53 AM

I will put this patch for new kernels at irregular intervals on my homepage:
http://www.azha.de

I think its more a BIOS-Failure form Acer than a Linux-Kernel miss. Therefore I don't think so, that this Patch will be ever in the Vanilla-Kernel.

I had the same problem with my Acer Aspire 1694 Wlmi and ASPLinux 11 (Russian clone of Fedora Core 4).
After modprobein'g ipw2200 module system message ("disabling irq 10, nobody cared bla bla" showed up) and my network card (tg3 module) didn't work any more. I've tried the posted patch - didn't help. Chanhed the kernel from 2.6.14 to 2.6.16 - didn't help. Reflashed bios to the newer version - didn't help. Then i started playing with the kernel options.
Before:
kernel /boot/vmlinuz-2.6.16-prep root=/dev/hda6 reboot=b pci=noacpi pci=usepirqmask quiet rhgb resume=/dev/hda7
After:
kernel /boot/vmlinuz-2.6.16-prep root=/dev/hda6 reboot=b pci=usepirqmask quiet rhgb resume=/dev/hda7

and it works now.
P.S.
I've used the pathed DSDT (as described here _h**p://djax.linuxbourg.ch/blog/?p=30) and had it built in into the kernel (as described here _h**p://gentoo-wiki.com/HOWTO_Fix_Common_ACPI_Problems (used method 3)). I don't know if this matters, so just in case.
Good luck.

It seems to be both hardware and software swtch.
If i press the switch on the front of the laptop (with a led), i get this awful error:

It disables the IRQ 10 and all the devices attached to it (my LAN card and sound card).
I've also tried acerhk module with the same result.

I'm beginning to panic! Anybody has any idea?

Thanks in advance.

You can do the following

su as root and then type ipw and tab to get the ipw start and stop commands

you get for 2100 you get ipw2100-start ipw2100-stop commands

first enter ipw stop command
then enter ipw start command

press function key and then the wireless switch

the wireless switch gets activated immediately

Please Note : This is hardware and software problem also.

follow the procedure as indicated and it would be successful

load laptop and wifi kernel patches, and all ipw(your number) drivers.

su as root

type ipw and tab bar
you get ipw.... ipw...start ipw...stop

execute the commands

ipw..stop
ipw..start

press function key and then the wireless switch, it will get activated.

I am following the practice successfully and have no problems with the my acer laptop.

every time you restart the computer and want to activate wireless switch, the same above procedure has to be followed
