LSI megaRAID controller: Kernel panic on virtual disk creation

[Saxena, Sumit]

Hi ,

While doing some testing on "mrsas" driver(LSIs' latest driver for next generation MegaRAID controllers- which will soon be submitted to upstream kernel), I am facing kernel panic  while creating Virtual drive(RAID0) on LSI controller-9286-e (6 Gb/s RAID controller). I am using latest upstream kernel.  The error message seen on panic is:

"reboot after panic: Provider da1 lacks sectorsize"

Below is the call stack:

----------------------------------------------
kdb_enter() at kdb_enter+0x3e/frame 0xffffff8000285920
vpanic() at vpanic+0x146/frame 0xffffff8000285960

fork_exit() at fork_exit+0x84/frame 0xffffff8000285bf0
fork_trampoline() at fork_trampoline+0xe/frame 0xffffff8000285bf0
--- trap 0, rip = 0, rsp = 0xffffff8000285cb0, rbp = 0 ---
-------------------------------------------------

"/dev/da1" is virtual drive created.

The problem does not seems to be related to <mrsas> driver. call stack indicates that panic is observed  in GEOM module.
Has someone face such issue earlier related to GEOM module?


Thanks,
