Hi all,

I have an HP pavilion ze4145 laptop running fedora core 1 with arjanv's
2.6.0-1.109 kernel. I have recently purchased an SMC 2532W-B 802.11b
wireless card. I am not sure that this is supported under linux, but
the problem I am having is rooted deeper than that:

when the redhat pcmcia script is run, the laptop locks up solid. sysrq
is enabled but i have not tried it yet, i'd have to look up the keys and
what they do. regardless, i have traced the problem to cardmgr itself,
cardctl works alright though it can't provide much info on the card. I
have pcmcia modularized as is most of the redhat kernel, and the modules
pcmcia_core, yenta_socket and ds are loaded. when cardmgr runs, it
locks the box up when it is inside the adjust_resources function in
cardmgr.c - at least on this 2.6.0 kernel, though the pcmcia script also
locks the box up on the 2.4 fedora kernels (2.4.22-1.2135.nptl and
2.4.22-1.2115.nptl, both fedora core 1 stock kernels).
the version of the pcmcia kernel stuff installed with fedora is 3.1.31 -
i have also installed the 3.2.7 userspace utilities (not kernel side,
the configuration process from pcmcia-cs-3.2.7 detected that pcmcia was
already enabled in the kernel and only installed the userspace stuff.)

the way in which i determined that cardmgr was at fault was by running
it by hand, simply cardmgr -v. I then traced it down further by adding
fprintfs to stderr to cardmgr.c - the specific line from which my box
never returns is

ret = ioctl(fd, DS_ADJUST_RESOURCE_INFO, &al->adj);

in adjust_resources() in cardmgr.c
the resource being adjusted is an io-range resource, and it's the second
one in the linked list that crashes my box, the first one succeeds just
fine

i also tried booting with noapic and acpi=off just to see if that had
anything to do with it, but no luck. I have not yet tried a stock
kernel.org kernel.

debugging this inside the ioctl is a bit out of my league, which is why
i have written this mail - any insight anyone else has (even if it's
just 'what the hell is wrong with you, you've screwed everything up by
doing xxx') would be much appreciated. Not being a kernel-hacker but
being a compsci major in school probably makes me too dangerous for my
own good. ;-) so if i've totally made a mess of things just tell me so. I've attached the diff between my modified copy of cardmgr.c and the one
from pcmcia-cs-3.2.7. First diff I've ever made, so it could be wrong -
it's just fprintfs to see where it got while it was running. I'll study
up on the format of adjust_list_t and see if i can figure out exactly
which io range the code is trying to adjust and failing at.

thanks for any insights, all.

Hi !

I've got a Compaq Presario 2118EA, which is the same kind of laptop if I
remerber correctly. I had this problem in the past until I modified the
the config.opts file in /etc/pcmcia to change the memory range and irq used.
I've attached config.opts with this mail.

Hope this helps
