I'm having trouble with ztdummy and I can't seem to figure it out. I am running Zaptel 1.4.12.1 under Debian 4.0 with latest updates applied and I have compiled Zaptel from source along with a new kernel from Debian sources to include 1khz timer support. The modules build fine, yet when I load them I get the following output from dmesg: rtc: lost some interrupts at 1024Hz And then Asterisk fails to load. I don't have any hardware in this box as it will be utilized for a pure VoIP solution so a hardware timing interface is not an option unless I can't get ztdummy to cooperate. What am I missing? I've been fighting this problem for a couple of days now... help appreciated :) Thanks, Stephen

I've seen some rtc issues with a Red Hat derivative where the motherboard was bad, others I've seen BIOS settings affect the real time clocks. I think I had a board once where I had to specify ACPI=no to the kernel, but I no longer have that machine so I can't verify that. But that 1024Hz lost interrupts was what I was getting and turning off the functionality in the kernel made it use a different clock for timing and corrected the rtc issues. -Ron

If positive, what would be the output of /proc/timer_list ? Cheers -------------- next part -------------- An HTML attachment was scrubbed...
