[asterisk-users] Digium b410p and 2.6.17 kernel bug?
Hi All
I have made the move to the Digium b410p BRI card and keep getting the
following intermittent kernel oops listed here in dmesg. I can make and
receive calls to sip devices fine. It only seems to happen when I call
from the Telco and hangup from the Telco before the audio paths on the
two end devices are connected.
I am using:
Kernel 2.6.17.14 compiled from source using config-2.6.9-22.ELsmp
from Centos 4.2.
asterisk-1.2.16
libpri-1.2.4
zaptel-1.2.15
I have tried disabling Hyper Threading and tried running on a non SMP
kernel but have the exact same result. Asterisk itself seems to carry
on running.
Output from dmesg:
