           Summary: ehci_hcd reverts to ohci_hcd under x86_64
           Product: Other
           Version: 2.5
     KernelVersion:  2.6.27-9-generic #1 SMP Thu Nov 20 22:15:32 UTC 2008
                    x86_64 GNU
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Modules
        AssignedTo: other_modules at kernel-bugs.osdl.org
        ReportedBy: igor.lopez at bredband.net


Latest working kernel version: Not tested on x86_64 earlier
Earliest failing kernel version: 2.6.27-7 (have not tried earlier)
Distribution: Ubuntu 8.10 AMD64, Fedora10 x86-64
Hardware Environment: HP Pavilion dv7 Notebook PC 
Software Environment: see above
Problem Description: USB HD and USB memory sticks does not utilize ehci_hcd
under 64 bit kernel (The very same devices works properly under i686 same
kernel releases)
It does not matter if I remove the ath5k and/or ATI/AMD fglrx module.
64 bit will not work but 32 bit will work.


Steps to reproduce: Insert (any?? I have tried a few different versions of
memory sticks and HD) USB memory stick or USB HD on above HW and fault will
occur.

Note!! Test on untainted kernel was only performed on 2.26.27.7 and if needed I
can perform the test without proprietary modules 0n 2.26.27.9.

I did not find a way of attaching normal debug info so they are included as
plain text with the following markers and taken from the Ubuntu dist:
 #uname
 #version
 #dmesg (added in following due to size restrict on comment)
 #lspci (added in following due to size restrict on comment)
 #lsusb (added in following due to size restrict on comment)

#uname
 uname -a > uname-a.log
Linux lopezdev 2.6.27-9-generic #1 SMP Thu Nov 20 22:15:32 UTC 2008 x86_64
GNU/Linux
