Based on some feedback, I decided to upgrade to vxWorks 6.9.3.2 (their latest) and ran into some new yet different problems. I debugged it down to an issue with how they were terminating early in the MP table scan if the MP tables did not have certain information in it. When I removed the early termination and allowed it to resume in spite of this particular data being missing, it suddenly was able to boot up successfully using the loapic timer! I am also no longer getting the error message that Andrew pointed out earlier. > > Thanks for the help, Andrew. Thats good news that you have managed to make it work. Which information is vxWorks expecting from the MP tables which is not present? If it is useful information then we might as well be presenting it. ~Andrew
