sort-of. But look:
akpm:/home/akpm> grep -i tsc dmesg-diff.txt +Marking TSC unstable due to: possible TSC halt in C2. +Clocksource tsc unstable (delta = -458965792 ns) -Marking TSC unstable due to: cpufreq changes. -Clocksource tsc unstable (delta = -150503296 ns)
the good and bad kernels seem to be doing quite similar things with the time management. But they're doing it at quite different places in the boot process.
