Hi , While doing some testing on "mrsas" driver(LSIs' latest driver for next gen= eration MegaRAID controllers- which will soon be submitted to upstream kern= el), I am facing kernel panic while creating Virtual drive(RAID0) on LSI c= ontroller-9286-e (6 Gb/s RAID controller). I am using latest upstream kerne= l. 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 kassert_panic() at kassert_panic+0x136/frame 0xffffff80002859d0 g_access() at g_access+0x3ba/frame 0xffffff8000285a60 g_raid_md_taste_jmicron() at g_raid_md_taste_jmicron+0x6d/frame 0xffffff800= 0285b00 g_raid_taste() at g_raid_taste+0x17f/frame 0xffffff8000285b50 g_new_provider_event() at g_new_provider_event+0xda/frame 0xffffff8000285b7= 0 g_run_events() at g_run_events+0x1a7/frame 0xffffff8000285bb0 fork_exit() at fork_exit+0x84/frame 0xffffff8000285bf0 fork_trampoline() at fork_trampoline+0xe/frame 0xffffff8000285bf0 --- trap 0, rip =3D 0, rsp =3D 0xffffff8000285cb0, rbp =3D 0 --- ------------------------------------------------- "/dev/da1" is virtual drive created. The problem does not seems to be related to <mrsas> driver. call stack indi= cates that panic is observed in GEOM module. Has someone face such issue earlier related to GEOM module? Thanks, Sumit
