#4 0xffffffff80477b82 in g_resize_provider_event (arg=0xfffff80007f8d3a0, flag=<optimized out>) at /b/mnt/src/sys/geom/geom_subr.c:668 668 KASSERT(!(pp->flags & G_PF_WITHER), (gdb) p pp->mediasize $2 = 0 It seems that r303637 really does cover the panic we're hitting since the g_resize_provider_event was posted with mediasize==0 which r303637 avoids. -- Regards, Bryan Drewery
