freebsd kernel with SKQ

Zero can be confused for a potentially valid value. For example, if I load and unload sbp driver I get a lot of messages like the following: fw_tl_free: the xfer is not in the queue (tlabel=0, flag=0x0) send: dst=0x00 tl=0x00 rt=0 tcode=0x0 pri=0x0 src=0x000 recv: dst=0x01 tl=0x21 rt=1 tcode=0x1 pri=0x0 src=0xffc0 KDB: stack backtrace: db_trace_self_wrapper() at db_trace_self_wrapper+0x2b/frame 0xfffffe04464407e0 fw_tl_free() at fw_tl_free+0x18d/frame 0xfffffe0446440820 fw_xfer_unload() at fw_xfer_unload+0xca/frame 0xfffffe0446440840 fw_xferlist_remove() at fw_xferlist_remove+0x2f/frame 0xfffffe0446440870 sbp_detach() at sbp_detach+0x1e0/frame 0xfffffe04464408e0 device_detach() at device_detach+0x80/frame 0xfffffe0446440900 devclass_driver_deleted() at devclass_driver_deleted+0x6a/frame 0xfffffe0446440940 devclass_delete_driver() at devclass_delete_driver+0x7d/frame 0xfffffe0446440980 driver_module_handler() at driver_module_handler+0xff/frame 0xfffffe04464409d0 module_unload() at module_unload+0x32/frame 0xfffffe04464409f0 linker_file_unload() at linker_file_unload+0x24b/frame 0xfffffe0446440a40 kern_kldunload() at kern_kldunload+0xbc/frame 0xfffffe0446440a70 amd64_syscall() at amd64_syscall+0x314/frame 0xfffffe0446440bf0 Xfast_syscall() at Xfast_syscall+0xfb/frame 0xfffffe0446440bf0 MFC after: 2 weeks |

This is the top level of the FreeBSD source directory. This file was last revised on: $FreeBSD$ For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information). The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7) and http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html for more information, including setting make(1) variables. The `buildkernel` and `installkernel` targets build and install the kernel and the modules (see below). Please see the top of the Makefile in this directory for more information on the standard build targets and compile-time flags. Building a kernel is a somewhat more involved process. See build(7), config(8), and http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html for more information. Note: If you want to build and install the kernel with the `buildkernel` and `installkernel` targets, you might need to build world before. More information is available in the handbook. The kernel configuration files reside in the sys/<arch>/conf sub-directory. GENERIC is the default configuration used in release builds. NOTES contains entries and documentation for all possible devices, not just those commonly used.
