Knoppix 3.3 hangs inserting a PCMCIA Compact Flash

**amontefusco** · 12-08-2003, 06:31 PM

I dont know if this is the right forum for my problem.
Feel free to redirect me to the correct one.

I have a MSI Hermes-651P desktop computer

http://www.msi.com.tw/program/produc...il.php?UID=418

with a PCMCIA slot.

I use a Knoppix 3.3 (19 nov 2003) both from CDROM,
and from HD (the system is working without glitches
with Slackware, Mandrake,RedHat and Window$ XP too).

Running Knoppix, inserting a 64 MB Compact Flash into slot 0, the machine hang.
The /var/log/messages follows:

---- Is now possible to mount the file system on the card

Last, the same card is working without problems on a IBM laptop
with the same Knoppix 3.3 bootstraped from CDROM.

Any suggestions ?

Thanks in advance

It is getting attached to the ide-disk driver instead of the ide_cs that the redhat install is using below.

Dec 8 14:25:26 andrewh2 kernel: ide_cs: hde: Vcc = 3.3, Vpp = 0.0

Now if the ide-disk driver works like the ide-cd driver and you can pass the option to tell it to ignore say a hdc which is a burner and you want it to use the ide-scsi instead of ide-cd so you can burn then you should be able to create a file in /etc/modutils/ and have the contents put into the /etc/modules.conf to have the option used at boot.

To do this create a file say pcmciafix in the directory /etc/modutils with these contents:

Code:

## Added by me to fix pcmcia being detected incorrectly as ide-disk
options ide-disk ignore=hde

Then you would run update-modules to update the /etc/modules.conf with the changes to be used for the next boot. Now this is just a shot in the dark with me assuming that the ide-disk works the same as the ide-cd driver I have never tried it so I'm not sure it will work, all of this done as root.

A last thought it may be as simple as modifying the append line in the /etc/lilo.conf and instead of there being a hde=scsi make it hde=ide-cs and then run /sbin/lilo -v to update lilo with the changes and have them used on next boot this done as root also, now this one is totally a guess. Anyways the problem is the ide-disk taking over the card when inserted instead of ide-cs so if these suggestions do not work that is where you need to start searching for the cause of the problem.

I did it

cat /proc/cmdline
BOOT_IMAGE=Linux ro root=304 hda=scsi hdb=scsi hdc=scsi hde=ide-cs apm=power-off nomce

but without luck.
Inserting the card I got again

Code:

the cardmgr is loading the correct module ide-cs but, as you pointed out,
the ide-disk prevails.
