Hi Ben, Currently what we are seeing on older RHEL 4 and 5 machine is that udev is looking through the entire '/sys/bus/pci/devices/...' directory and reading the vpd contents. When this happens our devices are hung before any user gets a chance to log in. Therefore, we need to prevent this from happening at boot time. Changing the permissions to root didn't solve our problem because we are running udev with root permissions. Thanks again. -Ben On Wed, 2008-07-02 at 11:17 +0100, Ben Hutchings wrote: > Benjamin Li wrote: > > Hi Jesse, Matt, and Ben, > > > > The following is a patch which is needed to prevent Broadcom 5706, 5708 and > > 5709 rev A. nics from hanging with the current PCI VPD code.
