Bug 5678

Please post:
- OOPS from 2.6.15-rc2-mm1
- kernel configs for -mm and vanilla 2.6.14
- full dmesgs for -mm and vanilla 2.6.14

Could you also try if 2.6.12 (or some earlier kernel) works?

This is gonna take some time for me; I will most probably need to make a clean
installation of some distro in order to try the vanilla kernels since my root
file system runs on reiser4.

However, I've tried using the card reader under a session of Damn Small Linux,
since it runs a 2.4 kernel. That gave no problems with card reader whatsoever.
Do you want me to try it with an earlier kernel in the 2.6 branch as well?

Last but no least; how do do I capture the OOPS? The kernel does crash
seriously, so there's really not much I can do after the crash. (Hmm.. just
realized I could boot with a live disk and grab the log-file, that way it won't
be overwritten).

I'll get to these things, but unortunately, it's gonna take some time..

logs+config; 2.6.14.3-vanilla

I hope this helps. These are all the logs from 2.6.14.3. I tried first with a
2.6.13.4-ARCH, and it led to oops+kernel crash. But there were no logs
containing those messages. These aren't in /var/log/kernel.log?

Anyway, I'm a bit in a confusion here. The pcmcia-cs packages isn't supposed to
be used? Cause that's what I've been trying with. If I don't start the pcmcia
services (with /etc/rc.d/pcmcia; part of pcmcia-cs), the kernel gives
absolutely no reaction on my insertion of a memory card.

Am I missing something here?

OK, upon removing pcmcia-cs the result really is that nothing happens
whatsoever. I insert a card and there's no response from anything anywhere.
Also, I don't have the /sys/bus/pcmcia directory.

But :
----------------------------------
[khashayar@nightfrost ~]$ dmesg | grep -i pcmc
pcmcia: parent PCI bridge I/O window: 0x3000 - 0x3fff
pcmcia: parent PCI bridge Memory window: 0xd0200000 - 0xd02fffff
pcmcia: parent PCI bridge Memory window: 0x30000000 - 0x33ffffff

pcmcia: parent PCI bridge Memory window: 0xd0200000 - 0xd02fffff
pcmcia: parent PCI bridge Memory window: 0x30000000 - 0x33ffffff
----------------------------------

Anything?

The easiest way to capture OOPS is to take photo of the screen with digital
camera :), the more time consuming method is to use serial console (or netcosole).

-mm contains bugfix for registering removable devices but it seems it is
something different (unsupported command causes device to hang? - we should
try to find which command causes ECC error), anyway kernel shouldn't OOPS
in such situation.

*** Bug 5680 has been marked as a duplicate of this bug. ***

To get PCMCIA working now, you need to issue these two commands:
modprobe pcmcia
modprobe yenta_socket

Also, see http://kernel.org/pub/linux/utils/kernel/pcmcia/pcmcia.html for more
information on the pcmcia-cs -> pcmicautils change

It seems I have had two problems. Firstly, the 'pcmcia' module was not being
loaded. Secondly, udev 068. With udev 068 (the version I used when originally
reporting the bug) the kernel would oops. But with udev 076 there is no such
problem. I'm still getting this in the logs though: 

-------------------------

-----------------------------------------

But the last output of "hde: hde1" only shows once (sometimes twice or thrice,
but no more), and I can mount the card no problem.

So, the question is: is this a bug with udev 068, and do you guys still want me
to post the oops (still looking for a digi-cam)?

It seems to me that this bug is solved?

Original IDE bug - yes but it seems that there are two other problems:
- udev-0.68 shouldn't OOPS the kernel
- IDE shouldn't send the unsupported command to the device

Khashayar, could you close this bug and open two new ones
(one for udev OOPS-ing kernel and one for IDE error messages).

Thanks!

Closing as pushed to other bugs (Master ECC is the flash card hardware crashing usually)
