clocksource unstable . . . testing utility ?

The clocksource tsc unstable (delta - xxxxxxxx ns) messages are not obvious anymore on boot up -
but still unresolved probably -
and I welcome any suggestions to try for the kernel append line in grub0.97 (Fedora 11) -
is one from google searches.

Although now I can boot direct to runlevel 5 with IceWM xorg as my gui,
I did before get plenty of practice appending the kernel arguments for runlevel 3 or single mode -
so now it is kernel arguments for clocksource and timer functions I will look at.

And then . . . just how do I get linux fedora to test them . . . ?

The primary nuisance is that (1) running testdisk analyse does not complete . . .
but even (2) just sitting in icewm will freeze clock - and then everything else mouse/keyboard/power switch -
all from if just the blue window sits with no visible processes running after about say 45 minutes -
or (3) even trying to run the find command using grep | time will stop the clock and freeze as above.

So, it is high time to resolve this issue.

And if - or when - I find something -
just how do I test that the clocksource(s), process timers and everything related are all as happy as can be ?
Are there timer benchmark tests like the cpu benchmarks that are in hardinfo utility ?

Ultimately, the goal is to get some real work - like testdisk -
to complete their task without freezing the system totally -
and timers are being looked at closer as the suspected culprit.

Thank you very much.

clocksource unstable

I note you never got a reply to your post. Did you solve the problem on your own or just (like me) give up in disgust. My Fedora 10 works great, but Ubuntu has not worked wince 7.10 (Gutsy Gibbon). I have downloaded isos and burned 8.04,8.10,10.04,10.10 thinking that eventually the Powers That Be would would unravel the problem. More joy in pounding sand down a rat hole.I have seen questions,complaints,frustration scattered all over the Linux community but none offering a final solution to the problem(s).

It has been suggested that NVidia graphic engine is somehow tied into this problem. For what it worth, here is what's in my system. MB Asus A8N-SLI premium (2005);CPU AMD Athlon 64FX;RAM 1G DDR DIMM 2700;Two Leadtec graphics Cards PX6800 TDH (NVidia);3 hard disks-WDC 74G SATA(Fedora 10);WDC 30.8G IDE(Windows XP);IBM 9.1G SCSI(Ubuntu). Lots of ancillary stuff not(?)pertinent to this discussion.

Please point me to a thread if you have an answer. Thanks, Les
