External hard disk causes kernel panic


Hi everyone,

I've just got one of those IDE hard disk caddies and put an old disk in it, and tried to connect it to my FC4 box (2.6.13-1.1526_FC4) with a USB cable.

After about 20 seconds it hangs the system with a kernel panic (see /var/log/messages below). It seems to work on my colleagues' box with is running FC2, and also before I put the hard disk in the caddy it used to be inside my machine. I've tried all the different USB ports, tried plugging it in then turning the power on, turning the power on then plugging it in etc.. USB works with my flashdisk ok so I'm a bit stumped. Anybody got any ideas?

Cheers,
Tim

Yes hotplug is installed (/sbin/hotplug)

The system works fine with flashdisks and also my ipod btw.

Cheers,

Actually does look like it might be a kernel bug of some sort. Is that the latest FC4 kernel available?
