Hi,

I installed RH8 on a SONY laptop and wondered whether the
firewire port could be the source of all my problems.......

Basically the system boots to the point where it says
detecting loopback interface then hangs - disabling kudzu
fixes the problem (so no hardware autodetect).

Downgrading to RH7.3 also fixed the problem. Obviously I'd
rather not cripple the system by disabling kudzu (this will
affect auto-detection of CDs/floppies??).

When the system was hanging I noticed error messages after
hardware detection began which I think related to the firewire
port.

Also it seems that these problems seem to affect a large number
of SONY laptops (which all have firewire). Given that there is no
way to disable firewire in the BIOS, is there something I can
change in kudzu or the kernel configuration to test my theory???


Thanks,

Jon.

Why do you think that disabling kudzu would cripple your system? As far as I was aware, kudzu was only used to check for hardware changes (such as hardware being installed or removed) and configure them for you. Why would stopping kudzu affect CD/floppy autodetection?

I didn't think it would cripple the whole system just automounting
of CDs/floppies - as it is it doesn't make any difference, CDs are mounted as per normal.

So disabling kudzu doesn't seem to have a drastic effect after all. However, I would still like to know what it's doing that's hanging
the whole system at boot time.

Any ideas?

I'm not sure why it would hang. There seem to be a few problems with RH8, whether this is yet another, I do not know. Do you know if your firewire is up and running? Can you do this and post the output?
As root, type lsmod

Any use?

Yep, that helps. You don't appear to have firewire modules (read: drivers) running. Again, as root, type in modprobe ohci1394 and then do another lsmod and post here. Cheers.

As suggested:

root@dhcp5 root]# modprobe ohci1394
Segmentation fault

I remember seeing messages about ohci before I disabled kudzu and
hardware autodetection was running - then of course it crashed....

Cheers,

Jon.

p.s. is there a way to stop the kernel trying to load this module (or detect the
hardware) such that I could run kudzu and use things like
USB mice etc....?

Hi Thymox,

Any ideas as to what's causing me such grief with firewire?

Cheers,

Jon.

Sorry, I'm not sure why you'd be getting a seg fault from that. You could try modprobing some other firewire 'drivers', such as ieee1394 and such, you should find a few in /lib/modules/kernel-version/kernel/drivers/ieee1394. I don't think that disabling kudzu would prevent you from being able to use USB mice and such.

Hi everybody: I'm experiencing the same problem with a Presario 2531 notebook. In fact Red Hat 9 hangs just when installing, while loading the ohci 1394 driver. I avoided it with the parameter "linux nofirewire"then it installed succesfully but when kudzu started for the first time it found my firewire port and then freezed again... what's wrong with firewire in red hat?????
I then deleted the line referring to the firewire in modules.conf, stopped kudzu and this fixed the problem.

My question: is it safe to delete the line in modules.conf which refers to the firewire? is it wrong?

thanx

ezrael
