Hi -
When I load/unload/load the megaraid amr driver I get a panic. I'm using
the latest -stable.
kldload -v amr.ko
kldunload amr
kldload -v amr.ko
(1) This panic is coming from xpt_bus_register() on 4073 in file cam_xpt.c:
new_bus = ( struct cam_eb*)malloc(sizeof(*new_bus), M_DEVBUF, M_NOWAIT);
(2) This malloc() is allocating 44 bytes for the new_bus structure:
In /sys/kern/kern_malloc.c on line 272:
kup = btokup(va);
if ( kup->ku_indx != indx)
panic("malloc: wrong bucket");
Any ideas? Is the amr driver not properly cleaning up the cam interface
when deregistering?
