In which case, I would try the effect of a) playing with the quotation marks, i.e. try " " instead of ' ' b) playing with the separator, i.e. try hdb,hdc hdb-hdc or even hdbhdc. strstr() only looks for the first occurrence of a substring, and has no concept of separators.

2.2.15 code is the same as the 2.2.10, as what regards this part. Adding
these extra printk showed me that the string ignore is composed only by the
first word, even if actually there are more than one. i.e if i put:
options ignore='aa hdb hdc'
it will just appear:
ide-cd: will ignore aa
I tried to find where does ignore come from and I found that it's determined
by a function called MODULE_PARM(), which does not belong to ide-cd.c so I
think the problem does not belong to the ide-cd module. But I couldn't do
anything more 'cause my programming knowhow is very limited. anyway, thanks
again for your hints.
Bye!

Only that the filename chosen for conf.modules or modules.conf
is not known by the person writing the kernel because the
kernel source and the distribution are unrelated.
Likewise, much documentation will assume that kernel sources are
unpacked and built in /usr/src/linux whereas Debian people are
encouraged not to do that.

Sorry, I hadn't noticed that Debian has changed filenames recently,
as someone else pointed out.

Well, after checking that the "ignore" has made it into the correct file,
and looking carefully for typos, then my reaction would be to put an
extra printk or two into the kernel source and see what it's actually
doing.
2.2.10 has:
MOD_INC_USE_COUNT;
printk("ide-cd: will ignore %s\n", ignore); <-
while ((drive = ide_scan_devices (ide_cdrom, ide_cdrom_driver.name, NULL,
failed++)) != NULL) {
/* skip drives that we were told to ignore */
if (ignore != NULL)
printk("ide-cd: checking drive %s\n", drive->name); <-
if (strstr(ignore, drive->name)) {
printk("ide-cd: ignoring drive %s\n", drive->name);
continue;
}
and I've added the two marked lines. If the string 'hdb hdc' doesn't
arrive intact at that point (for example, a character has been stripped
off or something), then you can try some workarounds, like
ignore='a hdb hdc a'. It depends what it prints out.
Cheers.

That's what i had already done, but it didn't change anything. ide-cd still ignores just one device. Anyway, thanks. Cheers.

Take a look at /etc/conf.modules (not modules.conf) and then follow the comments, i.e. put your options into /etc/modutils/local and then update-modules.

problems with "options" in modules.conf
Hi people, I have a quite strange problem with the Debian potato: I want my cdrom reader and writer (hdb and hdc) to be ignored by the ide-cd module driver, in order to activate for them the ide-scsi module and use as normal SCSI devices. In ide-cd.c it's written that I should put in modules.conf: options ide-cd ignore='hdb hdc' and that's what I did. The problem is that ide-cd only ignores hdb, but still recognizes hdc. This thing does not happen if I write, directly from the command line: modprobe ide-cd ignore='hdb hdc' In this case ide-cd ignores both them. It all seems very strange. Anybody knows anything about this problem? I thank you all in advance. Bye!
