>Description:


This is a brand new installation.

The panic also occurs with the GENERIC kernel.

Boot device is a SCSI disk on a seperate controller.

Before the drive is setup for use as a ZFS device, the kernel identifies
it as:
kernel: twed0: <Unit 1, JBOD, Normal> on twe0
kernel: twed0: 152627MB (312581808 sectors)
kernel: GEOM_LABEL: Label for provider twed0p1 is msdosfs/EFI.

This is a Western Digial, WD1600JS SATA drive, connected to a 3ware
8002-LP card (2-port SATA, PCI).

Last time the drive was used in a different computer and OS, it was in
good working order.

 After the device is setup for use with ZFS (via :zpool create ..."
command), at the next boot, the kernel panics when it begins to scan the
attached disks.  (Just after the "Waiting 5 seconds for SCSI devices to
settle" message.)

 What's interesting is that different SATA drive on the same port of the
same card does not cause the panic. The "good" drive is a Western Digital
WD360 (SATA, 36 GB).

boot-time kernel output:

twe1: 152627MB (312581808 sectors)
GEOM: new disk twed0
GEOM: new disk twed1

Automatic reboot in 15 seconds - press a key on the console to abort

>How-To-Repeat:

Do "zpool create poolname $dev".

Reboot the machine.

>Fix:

disconnect the drive. (not much of a workaround. :)
