Hi !

 checking up on 3.1 for the workshop CD on a AMD Duron 1.6 GHz compiled
 RTAI for 2.6.7 with default settings (make menuconfig -> save) make 
 make install (all thmoth) but the jitter tests show a problem. run the
 first time they seem ok - stoped with <CNTRL>-<C> and restarted I get
 the following output (reproducible with a sligth variation of absolute
 values).

AMD Duron 1.6GHz
platform Slcakware 10.0
Kernel 2.6.7
Patch hal7-2.6.7

 Anybody else seeing this ?
