Comment 17 for bug 1041883

I can't give you specific pointers as I am in no way a kernel developer ;)
but what it seems SSD users have this problem, while HDD users don't (might
need more confirmation). So somewhere the execution of the program depends
on a timing element. When booting from hdd, the boot is so slow that this
timing is correct, when booting from SSD, this timing is off, because the
system boots much faster.

This also explains why the module works properly in recovery mode followed
by 'resume normal boot', as the boot is much slower then (because it waits
for you to confirm 'resume normal boot').

The project lives here: http://acpi4asus.sourceforge.net/
