It's been doing this ever since I compiled a 4.5-p4 kernel on March 25th. I cvsup'd to 4.5-p5 and recompiled, but it's still crashing. It was initially showing nmbd as the current process at the time of crash. I disabled samba, thinking that it might be the culprit. It continued to crash, now showing the crash process as named. In both cases the kernel crashed whilst processing an ioctl (according to the crash dump). My problem seems somewhat similar to this one: http://spitfire.velocet.net/pipermail/freebsd-stable/2002-March/027982.html Has anyone else seen this? Any theories? Or fixes?!
