Also, I did confirm that these items will work under windows. John, your machine has invalid ECDT table, values for command and data registers are reversed. Please check if there is an update of BIOS for your machine and if there is none, please attach output of dmidecode here. Created attachment 19841 [details]

A quick hack that makes it work for me
Alexey,
If I take the unpatched ec.c from 2.6.28, and change it to make it use the previous ASUS workaround, it works on my laptop.
Maybe my ECDT from my DSDT is bad too. See my attached patch to see what I did.

cumulative patch for 2.6.28 to check ECDT #3
John,
Your DSDT is good. 0x66 port for command and 0x62 port for data.
This is my patch, which is broken... Please try new version.
The new patch worked. It didn't patch cleanly against 2.6.28, but I was able to patch it by combining part of it with patch #2 (from comment #13). Thanks for your help! John, can your laptop work well in 2.6.29? Alexey, it seems that the patch in comment #16 is not upstream, what's the status of this bug? You are correct, Zhang. 2.6.29 still doesn't work. I had to reapply the patch from comment #16. Created attachment 20766 [details]
Updated patch for 2.6.29
This is the same patch updated for 2.6.29.
patch in comment #20 applied to acpi-test shipped in 2.6.30 merge window (Linux-2.6.29-git14) closed. |
