Running 9.1-PRERELEASE currently.
Just set this server up, imported the pool from OpenIndiana 151 I
believe it was.
When I access (simply `ls`) certain files/directories, the system
panics. These files have ACL properties set on them from the Solaris system.
This system has 32gb of ram and only 8gb swap setup, so I do not
currently have a kernel core dump. It's also practically a production
machine, so I do not have much leeway in testing on it.
backtrace:
>From running ls(1):

At first I thought this was related to MAC / ugidfw, but I am able to
reproduce with those not compiled in. FWIW, here is a backtrace from
having that enabled:
panic: avl_find() succeeded inside avl_add()
avl_add+0x4b

Is there some easy way to clear these ACL properties on the files? I do
not need them.
Any suggestions on how I might fix this or debug this further?
