Hello, all! I'm running RTL 2.2 with kernel 2.2.14 as downloaded from your site on a small device containing a AMD SC410 and 8 Mb RAM and a cs8900 ethernet controller. Running the measurements-program provided with the RTL gives me a jitter of about 100 microseconds, usually -100000 to 0. Surprisingly, this is affected by linux programs. Running "find /" on a telnet session gets measurements as much as about 50 microseconds too late. Also the readings are different depending on wether the monitor process runs or not. Interesting: with monitor, the values are more negative:-) Can anybody out there explain, why this happens? Normally, I would expect that there is no influence at all from linux processes on the rt threads, right? BTW: I compiled the kernel with APM off! Thanx for any comment on this. Stephan Hoffmann
