I made some progress on my T61p. git from yesterday + a revert of commit e39ad415ac15116df213dfa2aa2a4f1b0857af9c Author: Mike Travis Date: Sun Jan 4 05:18:10 2009 -0800 cpumask: use work_on_cpu in acpi-cpufreq.c for read_measured_perf_ctrs makes cpu hotplug working again. Resume from suspend to ram is still broken on my Thinkpad. Looks like there is yet another patch to find.... Ingo, Mike: reverting e39ad415ac15116df213dfa2aa2a4f1b0857af9c fixes cpu hotplug on my thinkpad. Any idea how to proceed? Should we revert that patch in Linus git until we know what was wrong? -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
