Sorry for the last "lspci" that was without -vv if you need I can provide it again with feisty beta.
I don't know if it can be an hint but with the same identical notebook but another Athlon XP Mobile the bug is not present. With Athlon XP-M 2000+ core Thorobred then CORRECT speed -> 1600 Mhz With Athlon XP-M 2400+ core Barton then WRONG speed -> 1473 Mhz instead of 1800 Mhz -- /proc/cpuinfo reports wrong frequeny for AMD Athlon XP 3000+ https://launchpad.net/bugs/71772 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
