Judging by the lack of "Super Hybrid Engine" on Asus product pages, this applies to all "701" models (4G/4G Surf/2G Surf). So Asus made a deliberate decision not to support it on this model. We have several reports that using it can cause the system to hang [1]. That said, it does not happen all the time. Some users do not experience it at all (and apparently wish to continue "right-clocking"). Check for the EeePC 701 using DMI. If met, then disable writes to the "cpufv" sysfs attribute and log an explanatory message. Add a "cpufv_disabled" attribute which allow users to override this policy. Writing to this attribute will log a second message. The sysfs attribute is more useful than a module option, because it makes it easier for userspace scripts to provide consistent behaviour (according to user configuration), regardless of whether the kernel includes this change.

The EC generates this event when the ODD eject button is pressed (even if the bay is powered down). Normally, Linux doesn't need this as we keep the SATA link powered up (which wastes power). The EC powers up the bay by itself when the ODD eject button is pressed, and the SATA PHY reports the hotplug. However, we could also power that SATA link down (and for that matter, also power down the Ultrabay) if the ODD is left idle for a while with no disk inside, and use event 0x3006 to know when we need that SATA link powered back up. For now, just stop asking for more information when event 0x3006 is seen, there is no point in pestering users about it anymore.

That's because the polling thread will only run if hotkey_user_mask is set and someone is reading the input device or if hotkey_driver_mask is set. In this second case, this condition is not tested after the mask is changed, because the brightness and volume drivers are started after the hotkey drivers. Fix tpacpi_hotkey_driver_mask_set() to call hotkey_poll_setup(), so that the poller kthread will be started when needed.

Rather, it seems to be "if this bit is set, enable radio on resume, otherwise disable it on resume". So, the proper way to prepare the radios for S3 suspend is: disable radio and clear bit 3 on the SBDC/SWAN call to to resume with radio disabled, and enable radio and set bit 3 on the SBDC/SWAN call to resume with the radio enabled. Also, for persistent devices, the rfkill core does not restore state, so we really need to get the firmware to do the right thing. We don't sync the radio state on suspend, instead we trust the BIOS to not do anything weird if we never touched the radio state since boot. Time will tell if that's a wise way of doing things...

This works around newer models which don't want the hotplug code, where we end up disabling the wired network device. My old 701 still works correctly with this. I can also simulate an afflicted model by changing the hardcoded PCI bus/slot number in the driver, and it seems to work nicely (although it is a bit noisy). In future this type of hotplug support will be implemented by the PCI core. The existing blacklist and the new warning message will be removed at that point.

Instead, they should extract the data they need either from a "driver data" parameter, or the "driver data" field of the object which they operate on. The "asus" variable can then be removed. In practice, drivers under "drivers/platform" can get away without using driver data, because it doesn't make sense to have more than one instance of them. However this makes it harder to review them for correctness. This is especially true for core ACPI developers who have not previously been exposed to this anti-pattern :-). This will serve as an example of best practice for new driver writers (whether they find it themselves, or have it pointed out during review :-).
