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
