Public bug reported:
There's a reproducible kernel oops on Ubuntu Jaunty with the latest
kernel (linux-image-2.6.28-14-generic) on x86_64.
When connecting a Seagate FreeAgent Pro 500 gigabyte drive to my
workstation through FireWire, the operation fails and there's a kernel
Oops in the logs (pasted below).
Also, when I disconnect the drive and reconnect it again without
rebooting, the system freezes immediately. There are no any entries in
the logs from that moment, the system doesn't react to magic SysRq key
combinations, and the Caps Lock and Scroll Lock LEDs on the keyboard
start blinking. The only option is to power cycle the machine the hard
way.
Here's the kernel Oops from the logs:
