[Asterisk-Users] E1 PRI problem with TE205P

[Phone Dev]

Hi all,
I've setup a PBX in production environment last week but we have immediatly
find out drop conversations and lot of errors (in asterisk logs) like:

	Apr 10 17:30:48 NOTICE[25154] chan_zap.c: PRI got event: HDLC Bad
FCS (8) on Primary D-channel of span 2


My configuration is:

Motherboard: SuperMicro P8SCT (Intel E7221 chipset)
	Hypertrading and APIC enabled
CPU: P4 3GHz
Digium TE205P
Digium TDM400P with 4 FXS module
Linux Centos 4.1 (kernel 2.6.9-22.Elsmp ) 
Asterisk 1.2.5 (using Asterisk at home 2.7)

On span 1 of TE205P (configured as T1 PRI) is connected to a Rhino Channel
Bank 24 FXS
On span 2 of TE205P (configured as E1 PRI) is connected to Telco E1.

Both digium cards (TE205P and TDM400P) uses IRQ 9 (APIC is enable and
"virtual" IRQ is 161) but TDM400 is not used for the moment and I'm going to
disable it if could be usefull. IRQ 9 is not shared to other PCI card
installed. I've disable USB.

I've read a new comment on
http://www.voip-info.org/wiki/view/Asterisk+hardware about a similar problem
using TE110P and same MB that was solved using Sangoma A101 card. 

So, does TE205P may not work correctly on a SuperMicro P8SCT MB ? Have I to
buy a new A102 Sangoma card ?
There is any configurations may solve this problem ?
I'm going to try to disable hyperthreading but I'm not sure it may help.
Any help will be welcome. 
Thanks,
