Yep. Right now they can't work with the 2.6.22 kernel. I know annoying 
kernel changes cause them trouble, but they don't respond with the speed 
they should. Most people want to keep their platforms fully updated, and 
for many that means the 2.6.22 kernel is going onto their system around 
now. They also keep poor notes. For example, when 3.1.0 became necessary 
to be able to use a recent kernel, finding out that is was necessary 
took some effort.

I've never had a panic, but I have no expectation of a smooth ride when 
updating the Sangoma drivers. Pain and misery is a more the norm. It is 
best to wipe out everything you can find on your machine related to 
wanpipe and zaptel before an upgrade. They seems to end up using bits of 
old material under some circumstances, causing strange results.
