How-To-Repeat: Insert the hard disk with Linux-server that has a ReiserFS partition.
And try to use gpart to remove this partition

Not sure exactly how to classify this, but perhaps someone on fs@ can 
evalute it.

Seems geom-related.

Hi,

As I see from `gpart show ad4` output and from screenshot ad4 disk
was part of software raid (partition type '253') and also it was
part of Linux LVM. Also, last messages before panic are:
GEOM_LINUX_LVM: Disk ad4s3 removed from pv0.
GEOM_LINUX_LVM:

I think panic occurs in this code from g_linux_lvm.c:

g_llvm_remove_disk(struct g_llvm_vg *vg, struct g_consumer *cp)
....

if (found) {
	G_LLVM_DEBUG(0, "Device %s removed.",
            lv->lv_gprov->name);
^^^^^^^^^^^^^^^^^^^^^^^^ - NULL-pointer dereference here
	g_orphan_provider(lv->lv_gprov, ENXIO);
	lv->lv_gprov = NULL;
}
