we currently have a big problem with our two Dell PowerEdge 1950 servers. They both have 2 Digium TE410P.
When we were with Asterisk 1.4 and Zaptel, everything was OK, but since we are with Asterisk 1.6 and Dahdi, the servers crash randomly and an electric reboot is necessary to recover a usable server.
When a server crashes, here it what it is showed :
_ CPU 1: Machine Check Exception: 0000000000000004
_ CPU 3: Machine Check Exception: 0000000000000004
_ Uhhu. NMI received for unknown reason 31 on CPU0.
_ CPU 2: Machine Check Exception: 0000000000000005
_ CPU 3: Bank 0: 3200000410000800
_ Do you have a strange power saving mode enabled ?
_ CPU 2: Bank 5: 3200001080200e0f
_ CPU 3: Bank 5: 3200000040100e0f
_ Dazed and confused, but trying to continue
_ Kernel panic - not syncing: CPU context corrupt
_ Kernel panic - not syncing: CPU contect corrupt
_ CPU 1: Bank 0: 3200000410000800
_ CPU 1: Bank 5: 3200000044100e0f
_ Kernel Panic - not syncing: CPU context corrupt
We tried to update the Bios, but not solved the problem. Thinking that the problem was an IRQ conflict between the two Digium card, we removed one but the problem was still here.
Hope you can help me.
Our configuration : PowerEdge 1950, Debian Lenny, Asterisk 220.127.116.11, Dahdi 18.104.22.168, LibPri 22.214.171.124.
Thanks in advance,
