Hi Juergen,
We recently did another quick test of core scheduling mode, and the following
failures were found:
1. live-patch apply failures:
(XEN) [ 1058.751974] livepatch: lp_1_1: Timed out on semaphore in CPU
quiesce phase 30/31
(XEN) [ 1058.751982] livepatch: lp_1_1 finished REPLACE with rc=-16
2. ACPI S5 crash:
https://paste.debian.net/1121748/
So in sched_slave() *vprev is already scrubbed.
I have currently no idea how that could happen, is vprev->is_running
should be cleared only a little bit later.
Will look into it more..
Juergen
