Comment 9 for bug 62990

Here's a partial solution that works at least on my A6Km. Fire up your text editor and point it at /etc/modprobe.d/blacklist. Add the following line and then reboot.

blacklist asus_acpi

For some reason the hal daemon in Edgy doesn't like this module (Asus notebook acpi extras) on the A6 series notebooks. This line will prevent the module from loading and make hald, suspend etc. work again.

The downside is you'll lose some acpi controlled functionality, like the LCD brightness buttons.
