<div>I installed the Digium T1 card on Dell Poweredge 2950 and the system crashed several times, we got a Kernel Panic and first though it was the OS so I switched from Fedora 7 to Centos 5.1. </div>
<div>Our server was alarming in our monitoring system, when our Infrastructure department investigated the issue they found that the server was locked up at the console. They had to do a hard reboot of the server to bring it back. The following information was pulled from the logs:</div>
<div><br>BUG: soft lockup detected on CPU#1!<br> [<c044b2a4>] softlockup_tick+0x96/0xa4<br> [<c042e214>] update_process_times+0x39/0x5c<br> [<c04196ff>] smp_apic_timer_interrupt+0x5b/0x6c<br> [<c04059bf>] apic_timer_interrupt+0x1f/0x24</div>

<div>I believe the issue may be related to a driver for Our Digium Interface.</div>
<div>Here is the versions we are running</div>
<div>Asterisk 1.4.19 </div>
<div>libpri-1.4.3</div>
<div>zaptel-1.4.10</div>
<div>Digium's TE220 PCI Express card with echo cancellation.</div>
