Comment 10 for bug 228633

Hang again when a 2.5" USB hard disk was connencted to make a backup (in the left side USB port, while mouse was in one of the rear ports).

Hard disk had various partitions (NTFS and EXT3).

I disabled wireless card in the laptop switch and I could reformat the disk (one partition Ext3), and make the backup, no mer hangs.

So its like something about wifi card or/and USB ports (i don't know if the rear USB controller).

When I connect a flash or hard disk, I usually suffer hangs. But not when I discconnet wireless card.

I have the touchpad disabled in bios at every moment.

Help, please. This is really a bug. No problems in five previous ubuntu versions.
