Hi Wolfgang, I finally found some time and did some tests with your config file and the shiny new 2.6.25.8-rt7 On Thu, Jun 19, 2008 at 04:04:10PM +0200, Wolfgang Grandegger wrote: > Hi Fu, > > Luotao Fu wrote: > Keep in mind that I'm running Linux on a rootfs mounted via NFS. I have exactly the same test configuration here. Again everything looks just fine to me. Depending on which debugging Option are turned on my max. results pended between 70 and 350 us. However I could not produce any peak worst case values, which are so far away from the average like in your case. Have you tried the new -rt patch on your board? Still any strange results? cheers Luotao Fu -- Dipl.-Ing.
