could cause a solid system lockup in the driver attach: These chips do not abort an access to the internal SRAM, when the driver set the software reset bit in the istat register. But the chip will never acknowledge the requested PCI bus transfer in the situation, causing an infinite wait and a lockout of other bus-masters. The problem has been reported for rev 0x11 of the 53c825a and rev 0x01 of the 53c875. Revisions 0x13 of the 53c825a and 0x03 of the 53c875 are known to support SRAM accesses, even in the software reset state.
This is the top level of the FreeBSD source directory. This file was last revised on: $Id: README,v 1.10 1997/02/23 09:18:39 peter Exp $ 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 and the contents of /etc. 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 with config(8) is a somewhat more involved process, documentation for which can be found at: http://www.freebsd.org/handbook/kernelconfig.html And in the config(8) man page. The sample kernel configuration files reside in the sys/i386/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 LINT contains entries for all possible devices, not just those commonly used, and is meant more as a general reference than an actual kernel configuration file (a kernel built from it wouldn't even run).
