https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=293085 Donn Seeley <donn@xmission.com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |donn@xmission.com --- Comment #4 from Donn Seeley <donn@xmission.com> --- I have now had two very similar crashes with FreeBSD 15, most recently with 15.0-RELEASE-p9. The crash looks like a race between moused and the usbus0 thread -- the saved value of 'x' on entry to _sx_xlock_hard() is a pointer to the usbus0 thread struct. The respective stacks seem to show a race between evdev_dtor() in moused and evdev_unregister() in usbus0. The fix in comment #1 looks like it probably solves the problem. Can we get it backported to 15.0? Thanks! -- You are receiving this mail because: You are the assignee for the bug.home | help
