If the system firmware is sending messages then the default assumption ought to be that it's doing so for a reason. > Maybe that can be solved through an 'ipmi=off' option, or maybe off should be > the default state for handling of these messages? You can disable the various ipmi_si probings via the tryacpi, trydmi and so on options. > In any case, I think you're going down the right path here by building this > into > the kernel but IMO there's still some upstream work to do so that we don't hit > users with 100% kipmi usage and no way of avoiding it. Sending enough traffic to keep kipmid at 100% for extended periods of time implies that there's a *lot* of traffic appearing. What's sending it, and why? What kind of responses are expected? Is the fact that we're sending nothing back upsetting it? -- Matthew Garrett | [email protected] _______________________________________________ kernel mailing list [email protected] https://admin.fedoraproject.org/mailman/listinfo/kernel
