This is another try to get my SMART Modular Technologies 
SM9FA2043IP280 4 MB linear flash card working.

I have compiled the 2.6.0-test9 kernel (from Debian), without applying 
MTD CVS patches, with devfs turned on.

This time I have placed my configuration and logs of my problem in 
http://www.miernik.ctnet.pl/mtd/7-kernel2.6/

Please look at 
http://www.miernik.ctnet.pl/mtd/7-kernel2.6/log/syslog-cut 
http://www.miernik.ctnet.pl/mtd/7-kernel2.6/mtd_debug
for the most useful logs. 

In syslog-cut I have placed * where there was a huge number of 
identical lines (except time).
That was when I tried to run 
/usr/local/src/mtd/util/mtd_debug erase /dev/mtd/0 0 4194304
I finally stopped it with ^C. 

It looks like my flash is detected as a MTD_NORFLASH, 
I'm pretty sure that this card is a NAND card, but I don't remember 
where did I get that confidence from :(

The chip inside the card is:
---------
Intel

E28F016SA
70   5.0V
120  3.3V
U84433T1C
1993

Flash
---------

BTW I found an old post about the chip: 
http://lists.infradead.org/pipermail/linux-mtd/2002-August/005677.html
Does it matter if it's inside a PCMCIA card? 

Interesting that in /var/log/syslog I found a line: 
Nov  4 17:48:27 tarnica kernel: Found: Intel 28F016S5

What can be deducted from that? 

BTW it detected it as a 28F016S5 while it is a 28F016SA. The former is 
a 5V only chip and the latter is a dual 5V/3.3V.

P.S. I found this:
http://www.tuxmobil.org/pcmcia_ci10249.html

BTW: I found this comment about CONFIG_MTD_JEDECPROBE: 
This option enables JEDEC-style probing of flash chips which are not
compatible with the Common Flash Interface, but will use the common
CFI-targetted flash drivers for any chips which are identified which
are in fact compatible in all but the probe method. This actually
covers most AMD/Fujitsu-compatible chips, and will shortly cover also
non-CFI Intel chips (that code is in MTD CVS and should shortly be sent
for inclusion in Linus' tree)

My chip on the PCMCIA card is for sure a non-CFI Intel chip. Does the 
above comment matter if the chip is on a PCMCIA card?
