Feedback:

Can the wording around this be cleaned up a bit?

Devices based on “ADI” or “RCC” hardware, such as the 4860, 8860, and potentially other similar models, may have issues with the ichsmb0 and/or ehci0 devices encountering an interrupt loop, leading to higher than usual CPU usage (NG 8916). This can typically be worked around by disabling the affected device. For example, by placing the following in /boot/loader.conf.local:

hint.ichsmb.0.disabled=1
This does not affect the 2220, 2440 or XG-2758.

In this thread:

It was mentioned

You only need ichsmb0 disabled.

Disabling EHCI also stops the error flood but it also disables the eMMC because that is USB connected in RCC-VE, including the 4860.

Based on that, I would suggest the wording be updated to remove the ambiguity around `may have issues with the ichsmb0 and/or ehci0`, to instead be worded as `will have issues with the ichsmb0.` We should recommend that all users of ADI hardware add that line to the file specified in the doc.

Additionally, I would remove referencing `NG 8916`. From what I read in the forums, that's an internal Netgate Ticket number. But it's confusing to me as a user, because I also tried to look that up to understand what this meant, but found nothing except a forum post from someone else asking the same thing, only to be told it's internal and we can't see it. I would suggest either removing the reference, or updating the doc to make a note that it's an internal Netgate ticket only available to Netgate employees.
