I can't seem to find it in git. Was it somehow obsoleted > by a different fix for the same issue (SMI flood during APIC > calibration)? Or is the upstream kernel still affected? We were asked for a solution for all affected architectures (in particular, also i386) which was more than we were able to do at the time, given that the pressure had been reduced by finding a BIOS fix for the particular situation on system in question. The APIC clock calibration code on i386 is more complex than x86_64, we saw no way to provide a high-quality, regression-safe, tested patch for that to upstream with a reasonable amount of effort. That aside, I still think the x86_64 patch is fine and won't cause regressions. It just doesn't help on 32bit systems.
