I'm using kernel 2.4.26 under Slackware 9.1 if that helps. Just to verify that it is indeed the Dectalk, I turned off speech and used Brltty only to read several emails, while repeating the same loop on another console of comparing the date with the system clock. It stayed stable. As soon as I started up the Dectalk speaking again, it started wondering again. When I started typing this message, it was within a few milliseconds, and is now over 4 seconds off. Since you were using it under Redhat, I'm wondering if the Dectalk driver is tuned for Redhat's faster clock rate? I recall when Redhat 8 came out, they tweaked a value having to do with the clock speed of the kernel or something, and a lot of people had to adjust jiffy_delta and delay_time in Speakup to compensate because it caused their synthesizers to be choppy. I'm wondering if adjusting those values might help? My jiffy_delta is 50, and my delay_time is 500 now, which are default values.
