System: FreeBSD laptop-unix.lan 5.2-CURRENT FreeBSD 5.2-CURRENT #3: Sat Apr  3 16:26:42 EST 2004     root at lowell-laptop-unconfigured:/usr/src/sys/i386/compile/LAPTOP-5.x  i386

[That's the working kernel; any updates from the middle of April or so on do not work.]

This has been happening, apparently, since the PCI power support went into -CURRENT.

>Description:

This is on a HP Omnibook XE2; I posted about it before, but didn't get
any responses.  The problems showed up when the power support was
added to -CURRENT.  I've tried making the power manipulations in
pccbb.c respect the hw.pci.do_powerstate flag, but all I could manage
that way was to eliminate the error messages without actually getting
the cardbus to bring up any cards.

There's some other information on the system on my web site at
http://be-well.ilk.org:8088/~lowell/systuff/laptop-problems.html
from my previous battles with AGP support.

Setting hw.cbb.debug and hw.pccard.debug didn't show anything that
seemed useful to me.  Someone who knows the register definitions for
the bridge chip might well have better luck. .  I'm attaching the
dmesg.

>How-To-Repeat:

I would be willing to offer access to this machine to help debug the
problem, but it isn't network-accessible when the cardbus isn't
working...

>Fix:

Not known; I tried disabling the power-setting functionality for cbb,
but that didn't fix the problem.  [It did reduce the number of
messages displayed, but otherwise the symptoms were unchanged.]
