The original problem, with the same symptoms, still exists in Kubuntu Dapper 6.06 with both default (generic) and k8 kernels. I don't include /proc/cpuinfo as this is the same CPU as the original problem report. Package version info follows:
Generic kernel: linux-image-2.6.15-23-amd64-generic / 2.6.15-23.39 linux-restricted-modules-2.6.15-23-amd64-generic / 2.6.15.11-1 K8 kernel: linux-image-2.6.15-26-amd64-k8 / 2.6.15-26.44 linux-restricted-modules-2.6.15-26-amd64-k8 / 2.6.15.11-3 Other: powernowd / 0.97-1ubuntu1 For the record: Workaround is disabling /etc/init.d/powernowd with: chmod -x /etc/init.d/powernowd -- System freezes whilst powernowd stepping up AMD64 freq (intermittent/hoary) https://launchpad.net/bugs/16961 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
