[Freeswitch-users] Reinstall FreeSWITCH after new kernel?

[John]

Henrik,

I and some others have had problems with the 100Hz Ubuntu 10.04 LTS 
kernel.  All appeared to work for some days but occasionally choppy 
calls occur, often only in one direction.  We run a Sangoma BRI card 
(B700) and the problem manifests on the outgoing path.  I have recently 
changed to the Ubuntu preemptive kernel (no kernel recompilation 
required!) which has the 1000Hz timer and low-latency interrupt 
response. After 10 days running so far, it appears to have cured the 
problem.

Installing the pre-emptive kernel:

sudo apt-get install linux-image-preempt linux-headers-preempt

You will need the linux-headers-preempt if you need to rebuild kernel 
drivers for any hardware (which I do).

You will be pleased to hear that you do not need to reinstall your 
FreeSWITCH installation; the whole job takes less than 5 minutes.
