This is on coreboot, right? I don't see a commit ECA5A947 in seabios, and I don't see how 5DBF1732 could impact mptable. I guess it's possible that 5DBF1732 could impact the interrupts as we no longer run a sipi on all the processors, but I don't think SeaBIOS should have to issue a sipi - if that is doing something that impacts the OS then coreboot should do it as part of initializing the processors. -Kevin _______________________________________________ SeaBIOS mailing list [email protected] http://www.seabios.org/mailman/listinfo/seabios
