I have some strange performance issues with v2.6.32.60, I upgraded a bunch of virtual machines which were previously running v2.6.32.59 just fine, and with the new kernel the same workload is two to ten times slower. I can't bisect easily so I tried disabling RDRAND (thinking that maybe it got used even though it's not supported, causing vm exits) and noticed that the prompt wasn't showing up. (And as it turns out, even after disabling ARCH_RANDOM the performance issues are still there...) -- To unsubscribe from this list: send the line "unsubscribe stable" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
