Disabling ACPI using pci=noacpi directive in grub menu.lst did not fix my problem !
So I have removed this useless directive from my menu.lst.
I am back to Edgy, up to a reliable solution would fix this annoying Feisty bug.
I hope this bug will be fixed in Ubuntu 7.10 Gutsy so that I could migrate to a newer version than Edgy...
