Summary: "power bug" in 2.6.17 PCMCIA support
Kernel Version: 2.6.17
Status: NEW
Severity: normal
Owner: linux-pcmcia at lists.infradead.org
Submitter: kempin at in.tum.de
Most recent kernel where this bug did not occur: 2.6.16.18 (maybe later kernels
work, too)
Distribution: Gentoo Hardened 3.4.5-r1
Hardware Environment: x86 laptop Fujitsu-Siemens Amilo D7800, TI CardBus bridge
Software Environment: kernel
Problem Description:
Since I've upgraded to 2.6.17 I can't get the PCMCIA support to work. The
kernel notices when cards are inserted or removed, but I get those "power bug"
error messages (i.e. the kernel can't apply or remove the power to the PCMCIA
cards). The "power bug" FAQ didn't help.
Everything worked fine in 2.6.16.18 (using the same compiler version).
Steps to reproduce:
* relevant kernel options: lapic pci=assign-busses
* modprobe yenta_socket
Note about the "pci=assign-busses" option:
I get the following messages if I leave it out:
PCI: Bus #03 (-#06) may be hidden behind transparent bridge #02 (-#02) (try
'pci=assign-busses')
PCI: Bus #07 (-#0a) may be hidden behind transparent bridge #02 (-#02) (try
'pci=assign-busses')
Those are the cardbus bridges. So I added it to the kernel options, but it
doesn't make any difference: With 2.6.16.18 it works (whether I'm using the
option or not) and in 2.6.17 it doesn't work at all.
Here's some more information. I couldn't find any significant difference
(except the error messages) in the output of dmesg, lspci and the iomem files
regardless of which kernel version. It just works with the older kernel and not
with the newer one.
Maybe it's just a mistake of mine. Thanks in advance!
