I wouldn't expect Kosaki's patch to fix this. Have you experimented with the SHARED, RECURSIVE, and PRIO_INHERIT flags of the mutexattr to see if this is the only configuration in which you see the problem? Understanding which of these flags are required to reproduce would help point at where to look in the code. Right now I suspect a futex key reference imbalance in the futex_lock_pi() code path. 2.6.29 includes changes from me on fault handling as well as key reference imbalance fixes in this area. Mikael, please let me know what your git bisection reveals. I'm trying to make time to do some testing/analysis myself, but I'm being kept very busy on other pressing issues right now, so I may not be able to respond as quickly as I'd like. -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug.
