Summary:                    BUG: soft lockup - CPU#0 stuck for 10s!
@dahdi_receive
Description: 
I'm running the elastix distribution, which recently switched from zaptel
to dahdi, I believe.

Now I frequently experience system unresponsiveness (console/net/etc) and
get these messages on the console and in dmesg.  dahdi_receive seems to be
on the top of the stack in each case.

Kernel is: 2.6.18-92.1.22.el5
Asterisk is: 1.4.24.1-0

Sorry I haven't done a build yet, but I saw a subsequent lockup in the iax2
module as well and am now chasing down a kernel bug that might be the real
problem.  I'll make a note here once I've tested that proposed patch.
