Description wollman 2012-03-05 20:30:09 UTC

In testing, when I pulled a disk from the shelf, the kernel panicked
with a page fault in geom_multipath.  I did not think to get a
screenshot.

Fix: 

Unknown.  I'm willing to backport mav@'s rewritten multipath code from
head if there's some reason to believe it will help.

New GEOM_MULTIPATH code was merged to 9-STABLE about two months ago. I 
believe that should fix your problem.

To submitter: it sounds like this may be fixed - are you still able 
to recreate the problem?

I haven't had time to backport the new version to 9.0, nor to actually
reboot the server we are testing to install a new kernel.  This will
get done when I need to put the server into production, assuming 9.1
isn't released by then.
