Hi Lei, can you please provide information, which system you are using. dmesg (please use apic=debug kernel parameter), output of lspci -nnxxxx (as root), This reminds me on some HP laptop issues, see https://bugzilla.kernel.org/show_bug.cgi?id=11715 https://bugzilla.kernel.org/show_bug.cgi?id=11516 The BIOSes on HP laptops somehow checked IO-APIC configuration and set trip_points differently (for unknown reason). But I need above debug info to sort this out. Thanks, Andreas On Thu, Mar 10, 2011 at 07:04:51PM -0500, Wang Lei wrote: > "Rafael J.
