Comment 1 for bug 543400

When I try to mount my disk (ST3500418AS, with karmic installed and working) on lucid (installed on another disk, with the same motherboard Asus A8VX), system displays this message:
"Error mounting: mount: wrong fs type, bad option, bad superblock on /dev/sdc5, missing codepage or helper program, or other error. In some cases useful info is found in syslog - try dmesg | tail or so"
dmesg | tail:

This problem occurred only with this specific combination of hardware. I try to run lucid LiveCD with this Seagate hard drive and another motherboards (two different MSI motherboards, newer than A8vx), and everything goes without errors; on my Asus - like above.
In karmic this hardware (Seagate disk and Asus motherboard) just works (with pci=nomsi grub command), so I think this is kernel bug.
