           Summary: dapper flight 2 amd64 - Targa Traveller 826 - kernel
                    can't cope with external USB mice
           Product: Ubuntu
           Version: unspecified
          Platform: amd64
        OS/Version: other
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: UNKNOWN
        AssignedTo: debzilla at ubuntu.com
        ReportedBy: dominik.bodi at gmx.de

Both the install cd kernels and the kernel that gets installed onto hard disk
cannot cope with external USB mice.
The mice will not work, dmesg shows this message:

[  731.982526] ohci_hcd 0000:00:13.1: Unlink after no-IRQ?  Controller is
probably using the wrong IRQ.

During installation, if an external USB mouse is connected to the computer the
installation cd kernel will fail to complete initialisation and the installer
will not load. If you do not use Expert Mode the you will see some error
messages about an unhandled interrupt. Interrupt number is 185 or 11 if one uses
the "nolapic noapic" kernel boot options.

The install CD boots normally if no USB mouse is connected upon bootup. An
installed system will boot even with a USB mouse connected.

I tried two different mice and both did not work. The mice work on other systems
and they did work on the same computer with
kubuntu breezy final installed.

The computer is a Targa Traveller 826, powered by a Mobile Athlon 64 CPU. I'll
attach kern.logs, lspci -vv and lsusb -vv output shortly. However, these outputs
were taken when no mouse was connected. With a mouse connected, lsusb would hang
up and never complete. I have added the dmesg message printed above to the
kern.log output.

My system contains a fresh install of kubuntu dapper flight 2 amd64, without any
updates installed. That also means the "generic" kernel gets used and not the k8
optimized one.

Apart from the installation, this bug is not very critical as the built-in
touchpad (PS/2 i think) works without problems. However, a nonexperienced user
may find himself quite dumbfounded and might not get the idea of disconnecting
the mouse for installation, effectively failing to install the os.
