Hi all experts,

Sorry for bother you!

I backport 5 acer-wmi patches and sent here for review. But, those patches didn't show up in openSUSE kernel git.

No news is a good news :)

As far as I checked, these are good to merge. Feel free to merge to 12.1 branch by yourself.

Another good way is to merge such patches into stable kernel. But since 3.1.x stable is dead, this won't work for 12.1 kernel,unfortunately...

Takashi

OK, I just pushed it to openSUSE 12.1 branch on git. Thanks a lot! Joey Lee

...

What should I do for next step?

Thanks a lot! Joey Lee

Git-commit: 461e74377cfcfc2c0d6bbdfa8fc5fbc21b052c2a Patch-mainline: v3.3-rc8 References: bnc#752673 Target-release: openSUSE 12.1

We have several reports which says acer-wmi is loaded on ideapads and register rfkill for wifi which can not be unblocked.

Since ideapad-laptop also register rfkill for wifi and it works reliably, it will be fine acer-wmi is not going to register rfkill for wifi once VPC2004 is found.

Also put IBM0068/LEN0068 in the list. Though thinkpad_acpi has no wifi rfkill capability, there are reports which says acer-wmi also block wireless on Thinkpad E520/E420.
