I'm trying to get my twinMOS mobile disk IV 512MB usb stick to work with fedora 2. When I insert the stick the following window pops up: Window heading: KWrited - listening on Device /dev/pts/0

And it has the following message: Message from syslogd@dsl-69-134 at Mon Sep 27 11:48:08 2004 ... dsl-69-134 kernel: Disabling IRQ #9

Then, my KEYBOARD stops working, and i need to reboot my computer without the stick to get it back....

Let me guess, you've got a USB keyboard. Something about the disk is causing the kernel to disable the USB interrupt, IRQ 9. So it won't listen to any events from your keyboard.

Do you have a USB mouse, too? You should be able to use the GUI to reset the computer, but without a working mouse, that's not possible, either.

Is there any chance you could borrow a PS/2 keyboard to watch what's happening?

Is there anything else interesting in /var/log/messages ?

It is on a laptop. Only the mouse is USB, and the mouse continued working. I've tryed it a little bit more, and the /dev/pts/0 has changed to 1 and now my keyboard & mouse is working, but the messages has lots of text:

Can you try booting with acpi=off (at the end of the kernel comand line: edit it in grub or in /boot/grub/grub.conf)? I know that it's not really a proper solution on a laptop, but it might help you find one.

I don't really know enough about the ins and outs of acpi to tell, but if acpi=off cures the problem, then acpi=noirq might be worth trying.

Ultimately, this should go to the Linux Kernel Mailing List and/or Fedora bugzilla and/or the kernel bugzilla, but I'd recommend getting all the debugging info you can first.

The messages file now contains the following:

The system also is not restarting correctly when i have inserted the stick. When i press the restart icon from the login screen, the screen goes black and the cursor is blinking.

I then have to press ctrl alt del. to restart it, and during this restart the screen continues to be black.

according to twinmos the stick is supposed to work with kernel 2.4 and above... thats why i bought it.

What does the acpi do?

And what is the correct way to mount this stick?

Sounds like things are getting further, then. What happens if you try mounting /dev/sda1 somewhere?

Yes, Its getting further... I can now mount /dev/sda1 to /mnt/flash (or wathever) when I have the ACPI=off.

I tryed to make the ACPI=noirq. Then the I rebooted, and the computer hang, right after the graphical boot said: setting hostname (or something.. I have norwegian text on it) Also the my usb mouse dident work during this startup (it normaly does work).

I then had to edit the kernel parameter from grub to make it boot.

I also has a Apacer handy steno 1.1 256mb disk, i was also able to make this work with the ACPI=off. The only thing here is that the Apacer stick is /dev/sda, even if only this stick is in the usb port.

Why does 1 of them use /dev/sda, when the other comes in as /dev/sda1 ?

I've added both of them to /etc/fstab as: /dev/sda /mnt/flash vfat noauto,user,rw 0 0 /dev/sda1 /mnt/flash2 vfat noauto,user,rw 0 0

Is this the correct way to do it? and if I set it to auto instead of noauto, will it then automaticly mount when I insert it?

Also, how can I disable the graphical boot to see wats going on when the hangs during the boot?

James was also earlyer talking about maby making a bugzilla entry about this.. Is this problem something to add to bugzilla, and if so.. how?

Many thanx for all the good help James!!

I have done this with Iomega Zip disks. Under Windows-DOS-OS/2, the zip disk is expected to have a partition table with one partition numbered 4 formatted as FAT. Under Linux this works out to hdX4 . I have been able to delete the partition table and create file systems directly on the raw disk and mount it using hdX . Windows chokes on a disk like this. Apple formatted zip disk use yet another scheme.

I assume that the USB flash disk might be accessible and modifiable in this way, although the partition scheme might be implemented in the device's firmware. Trying to change these settings might render the device unusable.

I have turned them off now, and got the following: Before the welcome to fedora..... I had some ACPI errors, it is too much text to write down and reproduce her, is there some way to log the startup text to a file or something?

Well, if you boot correctly, you can look at /var/log/dmesg. That gets over-written each boot, though. That's at around line 843 of /etc/rc.d/rc.sysinit: you could alter this file (carefully) to make it save the log somewhere else, and earlier or later.

After the welcome i got the following: (Freely translated from norwegian to english) Setting hostname localhost [OK] Initializing USB controller (ohci-hcd) [OK] Mounting USB-filesystem [OK]

Then the system hang....

That's around line 220 of the same file. How are you at shell scripting? Can you put echo statements in at suitable places, so we can see where everything is hanging?

Is there also a way to keep the whole starup in English instead of norwegian?

It looks like this is picked up from /etc/sysconfig/i18n by about line 20 of /etc/init.d/functions.

There are a number of ways of making sure that LANG gets set to en_US, en_GB, or C.

Hope this helps,

James.
