Is there an knoppix-installer or a SCSI driver problem?

[Calvi Risorta]

Hello all:

In all, I have three recently downloaded Knoppix 3.4 CDs.:

04/05/2004
10/05/2004

and

17/05/2004 ....

But it happens that only the first one (the first 3.4 version?) can boot kernel 2.6 (using cheat code [knoppix26]).

The other two (which are newer versions of the Knoppix CD) will refuse to boot into kernel 2.6, ending with this error message:

-------
Can't find KNOPPIX filesystem, sorry.
Dropping you to a (very limited) shell.
Press reset button to quit.
-------

Whatever was changed between the first 04/05/2004 version and the next two versions probably has to do with the problems we are experiencing.

See my other posts regarding a zero length initrd.img-2.6.5 file ....

Basically, what seems to be happening is this:

(by jdtommy)
When I use the knoppix-installer it gets through the whole process and gives a fatal error at the end saying the modprobe failed and it creates the 0 length initrd.img-2.6.5 file.

Independently of all of the above, once Knoppix HD install is done, at boot time we can see these two error messages:


mount: devfs fs type devfs not supported by kernel
-------
-------
SCSI subsystem driver Revision: 1.00
kmod: failed to exec /sbin/modprobe -s -k scsi_hostadapter, errno = 2


I have a gut feeling that all of these symptoms/error messages could have the same origin and be related to a SCSI driver issue.

Knoppix 3.4 Version 04/05/2004 boots the 2.6 kernel while loading aic7xxx.0, megaraid.o and a100u2w.o (says it detects RAID which I don't have ...)

Thanks in advance for any pointers or input,

CIV

PS: Fabian F., are you there?

* V3.4-2004-05-10 (small updates)
- removed some scsi modules from the regular knoppix26 (Kernel 2.6) startup
because they are unstable. Use "expert26" to load them.
- Added script for generating bootfloppies in Knoppix "Utilities" menu
- Harddisk installer update from Fabian Franz
- "knoppix splash" fixes
- timezone and language setting add-ons
- added linlinc1 for captive-ntfs for download capabilities
- changed some e100/eepro100 network driver entries in hardware detection
- the usual debian package updates

Hello again:

Thanks for the post, horo.

But the problem still remains:

-------
04/05/2004
10/05/2004
and
17/05/2004 ....

But it happens that only the first one (the first 3.4 version?) can boot kernel 2.6 (using cheat code [knoppix26]).

The other two (which are newer versions of the Knoppix CD) will refuse to boot into kernel 2.6, ending with this error message:

-------
Can't find KNOPPIX filesystem, sorry.
Dropping you to a (very limited) shell.
Press reset button to quit.

The version you make reference to (10/05/2004) does not boot the 2.6 kernel. The only one that boots the 2.6 kernel is version 04/05/2004.

I have come across some more information related to this:

SCSI subsystem driver Revision: 1.00
kmod: failed to exec /sbin/modprobe -s -k scsi_hostadapter, errno = 2

errno = 2 means that the file scsi_hostadapter is not there.

If I am not mistaken, this (scsi_hostadapter) file that modprobe is looking for should be somewhere in the /lib/modules/2.5.4/scsi/??? directory.

But it is not (at least I cannot find it anywhere on disk).

Does anyone have an idea as to what's going on here?

Thanks in advance,

CIV
