Hi Richard, uml hackers
Since some time my "echo t > /proc/sysrq-trigger" stopped producing the proper
global back-traces for all Kernel threads.
All I get is:

..... etc ...
Single line statistics per thread. I'm based on "make defconfig" plus some
additional "YESs".
Is there something more (new) I need to set to get this working? If not do you
have a theory
or I should start bisecting?
(Using Fedora 18 um image, on Fedora 18 host 64bit both)
Thanks lots in advance
