From mboxrd@z Thu Jan 1 00:00:00 1970 From: Pierre JUHEN Date: Mon, 20 Aug 2001 19:33:43 +0000 Subject: PROBLEM : PCI hotplug crashes with 2.4.9 Message-Id: List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable To: linux-hotplug@vger.kernel.org [1.] PCI hotplug crashes with 2.4.9 [2.] hotplug causes the system to crash with kernel 2.4.9 (same configuration with 2.4.6 was OK). A manual run of "/etc/rc.d/init.d/hotplug start" shows that the system crashes immediatly when the system starts to scan the PCI devices. Only the first line "pcimodules scanning 00:00.0" is displayed. No trace is written in /var/log/messages.
