>Description:
      Checking parity with gvinum (the launched command is "gvinum checkparity -f -v raid.p0") causes a kernel trap. Reply me by mail if you want the complete trap.

When I used vinum (with FreeBSD 5.2.1 RELEASE), the "vinum checkparity -f -v raid.p0" completed successfully.

Here is my dmesg:

>How-To-Repeat:
      Lauching the "gvinum checkparity -f -v raid.p0" causes the kernel trap every time, but not a the same moment (sometimes after having checking 3GB, sometimes 11GB...)
