Subject: [uml-devel] sysreq t back traces stopped working please help
Date: Thu, 27 Feb 2014 21:05:13 +0200 [thread overview]
Message-ID: <530F8C69.9080801@panasas.com> (raw)
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
Boaz
