no longer have the parent in the device tree. This causes the identify function in ipmi_isa.c to attempt to probe and poke at the ISA IPMI interface Move the check for ipmi_attached out of the ipmi_isa_attach function and into the ipmi_isa_identify function. Remove the check of the device tree for ipmi devices attached. This probing appears to make Broadcom management firmware on Dell machines crash and emit NMI EISA warnings at various times requiring power cycles of the machines to restore. Bump MAX_TIMEOUT to 6 seconds as a hack for super slow IPMI interfaces that need longer to respond to our intial probes on startup. Tested on Dell R410, R510, R815, HP DL160G6 This is MFC candidate for 9.2R Reviewed by: peter MFC after: 2 weeks Sponsored by: Yahoo! Inc.
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, the most commonly used one being ``world'', which rebuilds and installs everything in the FreeBSD system from the source tree except the kernel, the kernel-modules and the contents of /etc. The ``world'' target should only be used in cases where the source tree has not changed from the currently running version. See: 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, documentation for which can be found at: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html And in the config(8) man page. 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 sample kernel configuration files reside in the sys/<arch>/conf sub-directory (assuming that you've installed the kernel sources), the file named GENERIC being the one used to build your initial installation kernel. The file NOTES contains entries and documentation for all possible devices, not just those commonly used. It is the successor of the ancient LINT file, but in contrast to LINT, it is not buildable as a kernel but a pure reference and documentation file.
