To add an addendum in the same thread...<BR>
<BR>
On day 5 for jnos my workstation with KDE froze requiring a re-boot.<BR>
Jnos continued to consume lots of CPU doing "nothing" prior to crash.<BR>
NO - I don't know the reason, I don't blame jnos, but crashing is highly unusual for my Linux.<BR>
What the crash caused is to apply all available updates and then pick up where I left off...<BR>
<BR>
In restarting jnos I had some problem with "attach asy ttyUSB0 ..." as "not found".<BR>
Yes - I am using a USB/RS-232 device - thus far thought to be good.<BR>
I consider this a "clue" to my cpu issue - in fact it is the culprit.<BR>
<BR>
When the USB device works OK during and after start-up, jnos likes it.<BR>
When the USB device is unplugged, jnos apparently looks for it even though idle thus saturating the CPU.<BR>
When the USB device is re-plugged, jnos user CPU reduces somewhat but the system increases so CPU remains saturated.<BR>
When jnos is restarted (with the normal USB device) all returns to normal.<BR>
The effects are repeatable (twice).<BR>
<BR>
Thus I conclude the CPU useage I reported is linked to the USB/RS-232 device.<BR>
Perhaps I have a marginal USB connector.<BR>
Perhaps if lots of USB devices become used then jnos will need some exception processing added, but not now...<BR>
The system crash? Nah - the jury is still out / FC-5 may have a bug or two...<BR>
I do like the feature set of FC-5 however - especially the software management improvements.<BR>

<FONT COLOR="#000000">Jnos is today in her 4th day of continuous operation since being started.</FONT><BR>
<FONT COLOR="#000000">My platform is FC-5 - jnos has truly little work to do and is generally idle.</FONT><BR>

<FONT COLOR="#000000">At start, CPU consumption was normal - once in a while jnos would contribute less than a percent (in 3-sec sample period).</FONT><BR>
<FONT COLOR="#000000">Today, jnos contributes a little less than 30% as user, 60(+)% as system.</FONT><BR>
<FONT COLOR="#000000">The change was probably in the past 24-hr period.</FONT><BR>
<FONT COLOR="#000000">Say 1/2 dozen other processes contribute a few percent so the total is say 96% CPU useage.</FONT><BR>
<BR>
<FONT COLOR="#000000">The remaining processes seem to have little trouble taking CPU for response to their own needs, so there is small perceptible change in over-all response time from the workstation. The only change I've found is on the KDE desktop switch-over. I have a 6-desktop configuration and at random times on only selected application windows is the change delayed over the normal say 1/4 second response time. The worst delay might be 8 seconds.</FONT><BR>
<BR>
<FONT COLOR="#000000">Thus my question to all: Am I alone in this effect?</FONT><BR>
<BR>
<FONT COLOR="#000000">I'm going to allow jnos to continue this way for a few more days to see if it is a precursor to failure of some sort.</FONT><BR>
<FONT COLOR="#000000">Let me know if there is something I should look for?</FONT><BR>
<FONT COLOR="#000000">JNOS simply doesn't release the CPU so it can sleep?</FONT><BR>
