I have a problem with a Dell 1850 and a TE410P card as do a few others who posted over the weekend. The problem in this case isn't so much echo but static and chop on all calls using ZAP channels. My zttest results look pretty much the same as yours. We were thinking it was the RAID controller but someone posted that they had the same problem with an 1850 without the RAID controller. We've got some E100P cards we're going to try out but it's difficult to troubleshoot this issue when it involves live PRIs.

Are you running vga=normal in your lilo.conf? (disable frame buffer) and running kernel WITHOUT apic and acpi support? (append='noapic acpi=off"). Making these changes, and disabling all other unused resources (to eliminiate IRQ sharing) got me to 100% consistently on a DELL 2850. -- =========================================Rod Bacon - VOIP Systems Engineer Empowered Communications Ground Floor, 102 York St. South Melbourne Victoria, Australia. 3205 Phone: +613 99401600 Fax: +613 99401650 ==========================================

I will do so this evening. Thank you.

It's the Intel 7250 (Lindenhurst) ? My 2650 has a ServerWorks GC-LE chipset. I'm wondering if that's part of the problem. I have a 2600 here that I will test this evening if your kernel option suggestions don't help. It has an Intel E7500 chipset. Maybe that's architecturally similar enough to the 7250 that I can get it to work. I hate to turn off SMP, but I'll do what it takes to get this thing up.
