>Description:
I created a test volume, afterwards i tried to delete it. rm -r <volume<, but the command did not delete all the plexes, so i issued rm -r on both plexes. The second one caused a kernel trap. Here the trap-screen:
Fatal Trap 12: page fault while in kernel mode
cpuid = 3; apic id = 07
fault virtual address = 0x0
fault code = supervisor write, page not present

>How-To-Repeat:
Maybe you caqn create a volume and 2 plexes and try to completely remove it, or try to remove a nonexistent plex. I know, one should not delete something nonexistent but on the other hand side the system should not crash if so ;-)
