I have successfully bootstrapped a Gentoo 1.0_rc6 system in the past,
and the PCMCIA stuff for that install CD worked great.
I am rebuilding system using Gentoo 1.0 install CD (going straight to
stage 3, having backed up /etc to a safe place, and then nuked all old
Gentoo install). The install looks about the same except that it detects
a SCSI subsystem that the 1.0_rc6 CD didn't find. Then if I insmod (or
modprobe) pcmcia_core I get what appears to be a kernel panic.
I lose control of the system and page after page of numbers (looks like
addresses, whatnot) go streaming by. I cannot stop it to see what they
are and I cannot capture the data.
Laptop is a Compaq Armada 1700. (I don't think this has anything to do
with the cards. Same result when no cards inserted.)
I have gotten system mostly working now. I didn't do any network stuff
and just installed the stage 3 tarball and other housekeeping. Then
rebooted using 1.0_rc6 CD. Enabled networking with this working kernel
and chroot-ed into the new 1.0 stage 3 I had installed. Was able to
emerge kernel-sources and will build from there.
If the Gentoo devs are following this, I thought they might want to know
that something in PCMCIA support changed between 1.0_rc6 and 1.0 that
makes the install painful, but no impossible. Certainly not for the
people that don't know to work around it somehow.
If I should file a bugzilla report, let me know. I suspect there may be
a kernel option around this or a module parameter, but am not
knowledgeable enough to know what.
Regards and thanks,
matt

I am not sure what to tell you. What changed was that we moved from a
semi-broken pcmcia-cs-3.1.31 to pcmcia-cs-3.1.33. Here are a couple
questions:
What happens if you modprobe i82365 ? That autoloads pcmcia_core, so I
would like to think that you get the same behavior, but it is something
to try. Exactly what steps do you use with the rc6 CD? Where is the
pcmcia_core module that you are insmod'ing?

You can file a bug, but I will need a bit more information, as the
modules on the 1.0 CD work fine for me.

Tried modprobe-ing i82365 and got the same reaction, probably because
pcmcia_core was pulled in as well (as you noted). With the rc6 CD, I'm just
booting, hitting enter a few times to get to the prompt and then "modprobe
pcmcia_core", "modprobe i82365", "modprobe ds", "cardmgr -f", "dhcpcd eth0".
Works like a charm every time. I did not try insmod directly, now that I think
about it, but I would presume that the modules are being pulled by modprobe
from /lib/modules or wherever they live on the rc6 CD (and the 1.0 CD).

Other than the above clarifications, I can't provide much more. As I said, the
laptop is completely disabled when I modprobe pcmcia_core. :^(
FWIW, I am now well on my way to getting GNOME back up, so I'm past the
problem. I thought I'd point out that the 1.0 CD didn't work for me in case
someone else comes along and has a similar problem.

matt

So pcmcia works on your 1.0 system, just not on the CD? OK, that is
kind of weird. I will find out what USE settings drobbins used to make
it. Maybe there is something there. At any rate, this is duly noted,
and I will keep an eye out for anymore problems.

Just because I don't want to mislead anyone, let me explain clearly what I
did:
- boot 1.0 CD
- preliminaries setting up filesystem
- unpack stage 3 tarball
- power down
- boot using 1.0_rc6 CD
- modprobe pcmcia_core, i82365, ds; cardmgr -f; dhcpcd eth0
- mount partition(s) with stage 3 tarball stuff installed, etc.
- chroot into stage 3 system
- emerge kernel source (since network now available)
- build kernel 2.4.19 using exactly the options I had used on my old
(completely functional, GNOME, X11, et al) 1.0_rc6 system (i.e. PCMCIA
completely modular, using kernel modules, etc.) and install
- configure grub to list new kernel
- emerge pcmcia-cs
- exit chrooted system, unmount, power down
- reboot into new kernel
- working networkable system
- begin emerging everything else
Another thing I should point out. Back when I was first using Gentoo (last
week and the week before) I was having problems with the pcmcia stuff in the
kernels I was building. In particular, the kernels wouldn't build unless I
enabled SMP (laptop != SMP) which I didn't want. With these SMP kernels, I
found that PCMCIA would give me the same "kernel panic" behaviour that I'm
having now!
It turns out that I needed to "make mrproper" after emerging the kernel
source. After that, I could actually build a uniprocessor kernel! Furthermore,
that uniprocessor kernel would not give me the "kernel panic" behaviour.
So perhaps this is related? The install instructions do not encourage a "make
mrproper" last I looked, but I have been doing it from here on out and haven't
encountered the same weirdness.
Regards,
matt
