I clearly know its weaknesses, and I believe Dmitry said, the HID bus/tiny driver way is the most ultimatest way very well. But (You may guess I will say this word :), before the HID bus or other better implementation come , I hope use the extended keys of my keyboard on Linux, and I guess other people also think same with me, so we need something here temporarily, even it do not merge into upstream code tree. And, I want to know that is somebody works on HID bus, Can I join it?

[BUG] acpi: failed to poweroff
Hi, all. I got a hasee notebook, and failed to poweroff after win soundcard (ALC861) problem. I seen someone said acpi=off may help this, but when I append it on kernel parameter list, the kernel even can not boot, the kernel just said "hdc: lost interrupt" at last, and freezeing. The dmesg is in the attachment. What do you need more? Any word is welcome.

If they have other weakless, tell me too. I also think the HID split plan is a great idea.

We can image, there are many devices use some HID base layer, however they even do not merge into mainstream kernel source tree for some reasons. and in fact, I do not like the mainstream kernel source tree include every drivers. For such devices out of core, we should have such feature that let developer write such driver quickly. I think it allows many monster-size driver modules is a better means than all-in-one.But we need resolve /dev/input/event? switching problem in principle first, else we still encounter same problem when new hidraw come.
