Panic in camisr() w/CTL in stable-9

[John]

Hi Folks,

   I've been giving CTL a try and thought things were going well.

   I installed a QLogic 2532 card in a ZFS server and a second in
a rh62 linux system. Src is current as this afternoon - r255479.

isp0: <Qlogic ISP 2432 PCI FC-AL Adapter> port 0x8000-0x80ff mem 0xfbdf0000-0xfbdf3fff irq 64 at device 0.0 on pci33
isp1: <Qlogic ISP 2432 PCI FC-AL Adapter> port 0x8400-0x84ff mem 0xfbde0000-0xfbde3fff irq 68 at device 0.1 on pci33

   I create a lun via:

ctladm create -b block -o file=/dev/zvol/pool0/testvol   -S serialnum-fc -d testvol
ctladm realsync off
ctladm port -o on -t fc
ctladm port -l
ctladm devlist -v

LUN created successfully

      num_threads=14
      file=/dev/zvol/pool0/testvol


   I can run commands against the lun from the linux side with
no problems. For instance:

# sg_inq /dev/sdc
standard INQUIRY:
  PQual=0  Device_type=0  RMB=0  version=0x05  [SPC-3]
  [AERC=0]  [TrmTsk=0]  NormACA=0  HiSUP=1  Resp_data_format=2

  [RelAdr=0]  WBus16=0  Sync=0  Linked=0  [TranDis=0]  CmdQue=1
    length=257 (0x101), but only fetched 36 bytes   Peripheral device type: disk
 Vendor identification: FREEBSD 
 Product identification: CTLDISK         
 Product revision level: 0001
 Unit serial number: serialnum-fc

# sg_readcap /dev/sdc
Read Capacity results:
   Last logical block address=209715199 (0xc7fffff), Number of blocks=209715200
   Logical block length=512 bytes
Hence:
   Device size: 107374182400 bytes, 102400.0 MiB, 107.37 GB



   However, when I try to partition the drive and format it, the ZFS server
panics with the following:

   This is on the client:

   I can replicate this on demand at this point so please let me
know if there is any information I can provide.


   Any ideas where to go from here?

Thanks,
John
