Hi,
I'm booting from USB GPT flash disk (amd64, 8.0-BETA2, r195712) and
I'm getting panic when running command "zpool import":
ZFS WARNING: Cannot open da0p2 for writting.
ZFS WARNING: Cannot open gptid/...... for writting.
Fatal trap 12: page fault while in kernel mode
cpuid = 0; apic id = 00
fault virtual address = 0x48
fault code = supervisor read data, page not present
...
current process = 2 (g_event)
I'm looking at sys/cddl/contrib/opensolaris/uts/common/fs/zfs/vdev_geom.c,
and maybe I'm missing something, but in function:
74 static void
75 vdev_geom_orphan(struct g_consumer *cp)
76 {
83 vd = cp->private;
84 gp = cp->geom;
91 g_detach(cp);
92 g_destroy_consumer(cp);
98 vdev_geom_release(vd);
g_destroy_consumer() will free "cp", but vdev_geom_release() later
will user "cp->private"

Everything should be made as simple as possible, but not simpler.
