acpi and linux
It can be used for Suspend and hibernate, CPU thermal temperature and other things. From Linux.org:
ACPI also has device drivers that control/monitor devices such as a laptop battery
So you can see, sometimes you need ACPI. If you have to disable it, perhaps you need to find out why it has to be disabled in the first place.
Also on the other hand. On my older IBM Thinkpads like with Puppy Linux I need to add acpi=force to the kernel line in /boot/grub/menu.lst because the bios is so old. If I dont add that line. My cpu temp isn't detected in conky. My battery gets no support in conky. And some Puppy distros won't shut down all the way. At least I can confgure acpi to how I want it to work in Linux.
Well if that's the case then why are there so many issues with it. It's not the distro because i've tried fedora, opensuse, ubuntu, mint, damn small linux, and all have the same issue. I've also tried different kernel versions with no help. the only thing that helps is putting the acpi=off in the kernel line on boot. It's also not just old systems cause I have a laptop that's a year old and had the issues with the wireless and network card in that system. I mean the hybernate and suspend I could care less about but on the laptop it sounds like it's a little more relivent. I've seen alot of issues doing my research through google and there are alot of different issues with alot of different hardware. What would be causing this issue and how can we fix it? I think this is a good issue to discuss and try to come up with a fix as a community. There should be an easy way to fix the issue and possibly pass the info along to maybe get the issue fixed in future kernels. Thanks for the posts everyone.
