Trouble booting Knoppix v3.8.2-2005.05.05EN

[Miles_Teg]

When I try to boot Knoppix on my desktop system I got the error described at the bottom of the page, so I booted with the following options:

boot: failsafe debug -b 1

It took 10 or so minutes of

hda lost iterupt
disabling IRQ #5

hdb lost iterupt
disabling IRQ #5

hdc lost iterupt
disabling IRQ #5

and so on (but it read the details of my hard and optical drives correctly) before reaching:

libata version 1.10 loaded
.
.
.
RAMDISK: Compressed image found at bock 0
VFS: Mounted root (ext2 file system).

Welcome to the KNOPPIX live Linux-on-CD!


Starting intermediate shell stage 1 as requested by "debug" option.
Type "exit" to continue with normal bootup.

I then typed exit and got the following message:

Looking for CDROM in /dev/hda

When nothing happened after five minutes I reset.

Can anyone suggest how to make progress? The CD boots fine on my laptop.


Cheers

Greg

I've booted Knoppix v3.8.2-2005.05.05EN on my laptop (A Dell Inspiron 8100) without problem. When I tried it on my desktop I got:

hdd: cdrom_pc_intr: The drive appears confused (ireason=0x01)
irq 18: nobody cared!
handlers:






[<c02356d8] (ide_intr+0x0/0x120)
[<c02356d8] (ide_intr+0x0/0x120)
Disabling IRQ #18
Welcome to the Knoppix live-linux on CD
Scanning for USB/firewire devices...... done
Can't find Knoppix filesystem, sorry.
Dropping you to a (very limited) shell.
Press reset button to quit.
Additional built-in commands available:
cat mount umount
insmod rmmod lsmod


etc, etc, etc.
The motherboard is an ASUS P4P800 Deluxe, with a P4/2.6 GHz processor and 1024 Mb of RAM.

Not being able to boot with "failsafe" suggests to me these possibilities:
- the CD cannot be read correctly
- the kernel doesn't have the module loaded for your CD-ROM
- some other kind of hardware issue, e.g. bad memory, special irq settings (pci=???)
- something else

The easiest thing to do is to run memtest: boot: memtest. The next thing to try is to burn a new CD at a slower speed, perhaps using a different CD brand. Just because the CD works in one machines doesn't mean it will work in another. After that, google using your motherboard and linux as keywords.

Let us know how things go.

Thanks Robert,

I ran boot: memtest for several hours. No problems. I use name brand memory (Kingston) so I didn't expect that to be the problem.

I booted it on a second laptop; it works on it and the original laptop without problem.

On one of the laptops I ran boot: knoppix testcd. All was well.

On the problem machine I switched boot priority and used another optical drive for booting (there are two optical drives on that machine: a Sony CD-RW CRX300E CD burner/DVD-ROM and a Sony DVD RW DRU-510A +/- DVD burner.) This didn't help. The optical drives work normally when used for other purposes.

A friend who was watching the test with the second drive thought Knoppix might be choking on my RAID 1 drives: on motherboard VIA VT6410 IDE RAID Controller with 2x Seagate 120 Gb drives.

I've booted Mandrake/Mandriva Move on this machine. It took longer to boot than I would have expected, and browsing the Internet was slow at first, but then it seemed to speed up to normal. Knoppix and Move run like greased lightning on my laptops.


I'd appreciate any more tips or suggestions. Would it help if the RAID array was hidden from Knoppix in some way?

Just because a CD works on other machines does not necessarily mean it will work on the machine in question. Writable CDs are wierd that way.

Two things to try:
1) burn a new CD slowly (<8x), possibly even using a different brand of CD-R
2) put the ISO on the harddrive and boot using the CD with the bootfrom= cheatcode

FWIW, a quick skim of Google results for the error message didn't turn up anything helpful.
