Sandisk flashcard reader on 2.4.2. It works. Sort of.

PLease Cc: all responses to mazur@xs4all.nl.

Hiya,

since I'm not on the list, and my experience with and knowledge of kernel 
internals are negligable, please keep in mind to Carbon copy all forcoming 
relevant conversation to me. Thank you.

Ok, I bought a Nikon Coolpix 990, aand to download the ppix to my Linux PC at 
home a SanDisk ImageMate SDDR-01.  That's parallel IDE.  At the time, I ran 
2.2.17, which of course didn't touch the thing with a 10 parsecs pole.  Som 
searching on the web led me to two conclusions:

1. This thing is either new or scorned.
2, There is a patch at http://www.electricgod.net/~moomonk/epat/ which may or 
may not help.

All the time during this story a 16 Mb SanDisk CompactFlash card is in the 
reader, unles otherwise specified.

So I applied the patch to the 2.2.17 kernel, remade, and rebooted.  No dice.  
Several kernel reconfigurations and rebots later still nothing, it seemed.  
So I downloaded and installed 2.4.2, which was mentioned to problably include 
the necessary features.  I copied .config from the 2.2.17, superficially 
checked the config, and remade and rebooted.

This was where I noted, that the parport, paride, epat and pd modules didn't 
get installed as modules at all.  I havnet dug into the why of that, let 
those familiar with the processes and Makefiles do that.  So I reconfigured 
to get those into the kernel, and remade and rebooted.  No dice, so I 
succesfully again applied the same patch, configured it into the kernel and 
remade  and rebooted.  No SanDisk. For some reason or another I rebooted 
again, and lo and behold,  we have a SanDisk.  I mount it ok, cd 
/sandisk/dir/, mv * elsewhere, my system hangs.  Reset.  cp * hangs the 
system as well,  so I do a for i in *; do; cp $i /there; sync; done;

The system hangs whenever I try to copy a certain picture.  (No, it doesn't 
contain nudiepixels.)  Luckily, I didn't care much about that one.  Since the 
start of this story and "now" I've aqcuired an 128 Mb card, and shot some 
pictures using it.  So I unmount my 16 Mb one, swicth cards, and mount the 
device again.  Or so I hoped.  System hangs on the mount operation.  And no
CTRL-ALT-DEL to go down more or less gracefully.  It really hangs, like 
whenever the patched system barfs on the SanDisk.

And today, several days later, the system even refuses to see the little 
bugger, even the lasst time, without any card it it's waiting little mouth.

So the message is: Yes, it could work, but with the patch from 
http://www.electricgod.net/~moomonk/epat/ it's slightly better working than 
without it.

What am I to do?

With kind regards,
Stefan.

It'll be because of the block device directory reorganisation I
expect, or something similar.  Double-check your config.

So the kernel you run which can see the SanDisk is with, or without,
the C7/8 patch?

Enable magic-sysrq and see if Alt-SysRq-B reboots the machine or not.
Or, even better, jot down what Alt-SysRq-T says.

This patch is in the queue, but behind the bug-fixes.

You might want to try fiddling with the BIOS options for the parallel
port and see if that makes any difference.

Config is fine, it's just make modules_install that's ignoring them.

With both 2.2.17 and 2.4.2, only with the patch, and it reports a c7 chip.
The only times it did get recognized the 16 Mb SanDisk CompactFlash card
(EC-16CF) was in the reader.  Though even that now doesn't seem to help 
anymore.  One clue only remains to be told: ever since installing the patch I 
get one error message lots of time: "invalid character 46 in exportstr for 
pd.drive0".  It's even printed at bootup from almost every init script.

It is in, and was in, I only had completely forgotten about that, never 
having had a need for it yet.

That, I figured.  Which is why I bothered the mailing list in the first 
place, so you know there are some issues with the patch as it is.

The only options I get in BIOS for my parallel port are Output-Only, 
Bi-Directional,  EPP and ECP.  ECP was the setting, and changing that to EPP 
and Bi_Directional only removed some of the protocols reported by the OS, so 
I'm back to ECP now.

I'll include a dmesg diff between one time he did recognize the thing and the 
current one:
