gvinum/ahc0

[Andrew Heyn]

Hi,
 
I have a gvinum setup and am using an adaptec 7899 controller.  Upon
removing a drive (testing gvinum), the following happens...
Is this message useful at all without a backtrace? Is there interest in
getting a proper backtrace?
I am running FreeBSD 5.4-RELEASE on a dell poweredge 1550 using one of
its two cpus.
