Title:
ppc64le oopses and userspace process hangs in System V semaphore code
Status in “linux” package in Ubuntu:
Fix Released
Status in “linux” source package in Trusty:
In Progress
Status in “linux” source package in Utopic:
Fix Released
Bug description:
Canonical have been hitting issues with the System V semaphore code.
Sometimes userspace processes would hang, sometimes an oops would pop.
We have been able to reproduce this. Michael Ellerman has taken a
close look and two fixes have just been merged in the 3.17 merge
window:
51d7d5205d33 (powerpc: Add smp_mb() to arch_spin_is_locked())
78e05b1421fa (powerpc: Add smp_mb()s to arch_spin_unlock_wait())
Could these please be merged into the Utopic and (eventually) the
Trusty kernel trees?
