Hi, i had some trouble with Grub2/android x86 RC2: famous " detecting Android-x86........... " with infinite dots.

finally resolved with moving all contents of /android-4.0-RC2 to main root ( / ) of partition...

so this is my 40_custom:

menuentry "Android ICS" {
set root='(hd0,3)' ##because /dev/sda3###
linux /kernel quiet root=/dev/ram0 androidboot.hardware=eeepc acpi_sleep=s3_bios,s3_mode SRC=/
initrd /}
on eeepc 900a with ubuntu12.04/android 4.0 RC
