Hi All, In the last week, my desktop has been disabled by disabling an IRQ several times.

For example, the box isn't using the firewire or usb7 ports; could I remove them, just to make sure it's the sata drives? How could I tell if this is a hardware problem as opposed to a bug? Is there other relevant data I should be considering? Thanks. Mark -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
