Greetings.
I have a Dell R710 with a mfi device (PERC 6/i Integrated) that panics almo=
st immediately on FreeBSD 9. It works fine on FreeBSD 8.2-RELEASE, but I've=
now had it panic in FreeBSD 9.0-STABLE and 9.1-RELEASE.
Output of mfiutil show adapter and panic backtrace below. Anybody seen this=
or have any ideas?
