Seems to be causing Firefox to completely lock up as soon as either right mouse button is clicked (for context menu) or a menu item is selected. Reverting to earlier kernel version makes the problem go away for me.
Also manifests itself using the latest stable release of Firefox (30.0) as downloaded from firefox.com, so I believe is not a Firefox issue. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1327300 Title: Regression in commit 8e4e453d548e3c24e9070eda23c52f210951b921 Status in “linux” package in Ubuntu: Invalid Status in “linux” source package in Lucid: Fix Committed Bug description: Phil Turnbull reported a problem with the Lucid (2.6.32) backport of futex: Always cleanup owner tid in unlock_pi commit: 8e4e453d548e3c24e9070eda23c52f210951b921 In patches-2.6.32.tgz:patches/0003-futex-Always-cleanup-owner-tid-in-unlock_pi.$ there is this change (ignoring whitespace changes): curval = cmpxchg_futex_value_locked(uaddr, uval, newval); - - if (curval == -EFAULT) + if (curval) ret = -EFAULT; which seems to change the behaviour of the function. The purpose of the return value of cmpxchg_futex_value_locked changed in 37a9d912b24f96a0591 "futex: Sanitize cmpxchg_futex_value_locked API" which is not included in 2.6.32. This patch changes the return value to a status code, but in 2.6.32 the return value is the value of the futex or -EFAULT. With this backported patch, any futex with a non-zero value will return -EFAULT.
