Thanks michael37. This one from your hosts resultlist is also interesting :
<core_client_version>6.2.18</core_client_version>

Did you change something around the 15th/16th april on your os, some updates possibly, because it looks like around that date the kind of error has changed from the above to the one you posted before. And furthermore there is a lonely completed and validated result reported today. How often does that happen ?
The kernel version 2.6.28-11-generic seems to be new and was not available when this AstroPulse app was initially tested. Maybe we have to rerun some tests with this new kernel version. Will start to look deeper into this issue to find out what is wrong, now.

Ignore this error totally, that was a bug with suspend/hibernate of the laptop.
The errors that concern me are the segmentation faults.

It is what it is, the recently released (ahem, as of today, April 23rd), version of Ubuntu 9.04 Jaunty Jackalope. Comes with new kernel, libraries, everything. Will be glad to help as always.
Urs Echternacht:
After rereading some pages of our testing forum for the current AP app i found that this same error was reported before. That person used a very old kernel version which was not fully capable/compatible with the newer features (< 2.6.22). So this could be some kind of compatibility issue. Will download the current (K)Ubuntu version over night and try out how it reacts on one of my T7200 hosts.
sunu:
Michael as a first step, can you update your boinc to 6.6.20?
I don't think it's strictly a kernel problem, more likely a combined kernel-library (libc?) problem.
A few questions:
Were all these wus done with the same kernel? What version?
The same questions for libc6.
Were these from the prerelease ubuntu? If they were, try with the official release.
Do you have activated any power saving options (speedstep, etc.)?
EDIT: That report that Urs is referring to had also an old boinc (6.2.15, yours is 6.2.18) so again please try 6.6.20.
