[Crash-utility] crash: cannot resolve "schedulers" crash-utility 7.1.5 withxen-4.7.0

[Guido.Rossmueller at gdata.de]

Hello everyone,

i have a problem with crash-utility 7.1.5 and xen 4.7.0


i have installed the kexec-tools for saveing the vmcore in case of a
Hypervisor crash. If i simulated this via xl debug-key C, i get the vmcore.
now, if i want to analyze this vmcore via crash:
crash --hyper /usr/lib/debug/xen-syms-4.7.0 vmcore

i got the follwing message:

crash: cannot resolve "schedulers"

if i execute this command with debug output:
crash -d3 --hyper /usr/lib/debug/xen-syms-4.7.0 vmcore
