Description:Hi Guys, I'm not having a lot of luck with my new Opteron :-(

I've submitted a bug, when trying to run asterisk compiled in x86_64 -(its bug 1820).

So, I reinstalled fedora core 2 and am running in 32bit mode.

I compiled the zaptel drives (CVS date 20040610) and the drivers detect my X101P and TDM400P - everything there seems good.

I then ran for a little while, a compiled version of asterkisk (1.0-stable) that was compiled on my old pentium III 450Mhz SMP box (RH 7.3) - asterisk runs very well (only tried for a day at most).

I made a small change to the source (changed #define DEFAULT_CIDRINGS 2 in chan_zap.c as I'm in Australia - saw this in google somewhere) and recompiled on Fedora Core 2 (32bit).

When I run my (FC2) compiled asterisk (1.0-stable) - it'll only run for a few minutes (sometimes 5mins sometimes 20mins), then my server panics - and it seems to panic more frequently when I'm using my FXS phone. Unfortunatley, the panic doesnt make it to syslog, as the system locks up, and I need to reboot.

Looking at the console, it seems there are many lines of panic output - so I cant even capture how the panic started.

When I revert back to my RH 7.3 compiled version of asterisk (1.0-stable), it runs very well.

I'm happy to help you guys any way I can to help you debug this - if you dont have a solution already.

(Wishing I could be running 64bit linux... :-)


System is: AMD Opteron on a Tyan S2882 board - 512MB
X101P & TDM400P (with 1 FXS).
Fedora Core 2 - 32bit - no updates so kernel 2.6.5-1.358

Anything else I can give you?

We've already seen a bug about this and the solution was to turn off optimizations beyond "-O" in the zaptel Makefile.  Seems to be some compiler bug with respect to x86-64.

i'm running a dual opteron on Tyan MOBO with kernel 2.6.5 and TE410p and did not see any of problems once i got it to compile.
(i'm on suse64)

Its not that fast though.

Any more input here?

markster - this might have been fixed by bug 1820 - I've recompiled (after the work you guys did for 1820) and it works a treat...

(I didnt make any changes to the makefiles for zaptel or asterisk...)
