New Revision: 191001
URL: http://svn.freebsd.org/changeset/base/191001
Log:
MFC r190946:
Fix recognition of kernel-mode traps that pass through the KDB trap handler
but do not actually invoke KDB. This includes recoverable machine checks
encountered in kernel mode.
This patch causes machines with Grackle host-PCI bridges to be able to
correctly enumerate them again.
