Hi Andrew... Thank you very much for the info.
I didn't recompile the kernel, Im using a generic 2.6 kernel but its worth taking a look at what you said.. Where can I find (which file) the Hz the kernel was precompiled to? Also, Im running 1 te110p and 2 tdm cards, probably I'll disable 1 card later but I will need at least 1 tdm and the te110p for my E1. So you suggest not disabling any apic/acpi stuff then.. How about HT? should I disable that on the bios? Im using supermicro servers and eventhough I get voice calls without problems, Im getting a few IRQ Misses from time to time which makes faxing on the E1 very difficult (the original problem). What do you think? |-----Original Message----- |From: [EMAIL PROTECTED] |[mailto:[EMAIL PROTECTED] On Behalf Of |Andrew Kohlsmith |Sent: Tuesday, April 11, 2006 7:37 AM |To: [email protected] |Subject: Re: [Asterisk-Users] te110p and interrupts | |On Monday 10 April 2006 19:20, Mojo with Horan & Company, LLC wrote: |> Try booting with apic off, I think it's noapic kernel |option.

The |reason that it is suggested to disable the IO-APIC is that on |many low-end systems, the IO-APIC is plain old broken and |causing other issues. I don't think I've run across a system |board in the last year or two with that issue, though. It's |always been on older P3 and early P4 systems. | |Anton, your problem is very likely simple interrupt load. You |have three Digium cards in there, and they're all generating |their own 1000Hz interrupt. |If you did the newbie thing and compiled your kernel with a HZ |value of '1000' because you felt it would be better, you have |that overhead as well. | |Your system is very likely just having trouble coping with so |many interrupts. |My personal opinion is that you should sell the three Digium |cards and buy a single dualspan card and a cheap channel bank. | Your interrupt load will drop by 2/3 and your system will be |FAR happier. | |So check the kernel HZ value first; I set *all* my Asterisk |systems to the old style HZ of 100; there is simply no need |for anything more on a server, |*especially* if you've already got hardware providing a real |1000Hz interrupt instead of ztdummy trying to emulate such a thing. | |-A. |_______________________________________________ |--Bandwidth and Colocation provided by Easynews.com -- | |Asterisk-Users mailing list |To UNSUBSCRIBE or update options visit: | http://lists.digium.com/mailman/listinfo/asterisk-users | | _______________________________________________ --Bandwidth and Colocation provided by Easynews.com -- Asterisk-Users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
