For each one I have to create a custom boot image for them to download and test (a.k.a. don't expect to hear from me soon :)) Hi Caglar, What's the microcode version? Get by "dmesg | grep microcode" if you success boot other version of kernel. Can you try to disable C-state(C6) in BIOS before your boot 2.6.27? Thanks -Youquan
