I am going to try a suggestion on there (after having re-read it ) and rather than use 0x28, I am going to give 0x20 a try (this seems highly related to your suggestion). If this does not work, I am going to read up on lptcontrol per your suggestion and see if there is anything that I am missing. Thanks for the info. If the 0x20 does work, I will re-post to this list, but since the messages I was receiving took hours for each one to appear, I will have to let it sit there for a while. > So, do you get any new messages, or less, from using polled/ > interrupted mode?

Perhaps as 5-STABLE matures, things are changing prompting a few more of these messages to come out. > > It's just a thought, but might provide more hints on what's wrong. > Maybe. > > Note that it doesn't matter if you write it in a device.hints file > or compile a kernel with polled settings, since the acpi setting > will hijack it anyhow!
