Hi, I plugged my HP Omnibook 4150 into my dock for the first time in a couple months only to discover that I couldn't attach any of the PCI devices in it. I'm running -current as of sometime in the last week or so. I traced the problem to the new PCI code comitted six weeks ago. Specificaly: - Make the PCI-PCI bridge code a little more paranoid about valid I/O and memory decodes. It looks like the new code is too paranoid. The following patch lets me attach devices in the dock though it's obviously bogus. You can find a kernel config, verbose dmesg output, pciconf -l -v output, and acpidump output at: http://www.one-eyed-alien.net/~brooks/FreeBSD/dock/ Please let me know if you need anything more from me to help debug this. Thanks, Brooks -- Any statement of the form "X is the one, true Y" is FALSE.
