Hi All,
While doing some testing on <mrsas> driver, I am facing kernel panic
inside GEOM module. I am using FreeBSD10.0 64bit, installed on Virtual
drive connected behind LSI MegaRAID SAS 9361 controller and two Enclosures-
Dell MD1220 with total 39 drives are connected to the controller. As I
convert unconfigured drives(connected to Enclosures) to JBOD(plain drive
without any RAID configuration exposed to OS), kernel panic is observed
inside GEOM module with below traces-

I have attached complete dmesg logs. Has anyone faced similar issue with
