Problem Description:   
kernel doesn't load correctly usb 2.0 devices using ehci_hcd module.  
They work only with ohci_hcd module on 64 bit installation or with ehci_hcd  
module on 32 bit installation.  
  
I've just documented my bug to this address:  
http://bugs.gentoo.org/show_bug.cgi?id=98100 with a lot of debug.  
  
Steps to reproduce:  
  
1. boot linux.  
2. attach a usb 2.0 device  
3. watch the log of /var/log/kernel/current.  
  
Sorry, but is my first bug report and I don't try a way to attach external  
files. So I put something here. Other logs are on gentoo bugzilla.  
  
They work only with ohci_hcd module on 64 bit installation or with ehci_hcd  
module on 32 bit installation

log output using ohci_hcd driver

Attaching device after having done modprobe -rv ehci_hcd loads correctly the
device.

log output with a 32 bit installation

That's the output using the driver ehci_hcd with a 32-bit installation, on the
same hardware.
Everithing works fine.
Comment 5 Andrew Morton 2005-07-28 23:53:56 UTC
Has there been any movement on this?

Is the bug still present in 2.6.13-rc4?

Thanks.
Comment 6 David Brownell 2005-07-29 13:06:39 UTC
This is likely an ACPI or BIOS problem.  We get all too many of them. 
In this case it's particularly suspicious that it works with a 32bit 
kernel but fails with a 64bit one. 
 
This should be transferred over to ACPI land ... 
Comment 7 Andrew Morton 2005-07-29 14:04:17 UTC
OK..

Marco, did any earlier 2.6.x kernel work correctly?  If so, which version?

Comment 8 Marco Clocchiatti 2005-07-30 23:46:30 UTC
Same behaviour on vanilla-2.6.13-rc4, gentoo-sources-2.6.12.r6 and 
gentoo-sources-2.6.9-r9. 
This thread: 
http://www.mail-archive.com/linux-usb-users%40lists.sourceforge.net/msg13143.html , 
shows the same problem on "2.6.10 vanilla and 2.6.10-1.1109_FC4 (2.6.11-rc2 
based)" kernels. 
Comment 9 David Brownell 2005-08-01 09:48:10 UTC
One more thing to check:  does this machine have more than 2 Mbytes
of physical memory?

NVidia looked at this and found an issue with NF4 EHCI not doing DMA
right except into the lower 2 MBytes of memory.  The guy was going to
resubmit the patch in mergeable form, but hasn't yet.  Some details
weren't clear, but that issue _might_ have been a 64-bit only thing.
Workaround was to set the DMA mask to ~(1<<31) on certain chips.

I've used NF3 EHCI with 64 bit kernels, no problem.  Less memory though. :)
Comment 10 Andrew Morton 2005-08-01 12:20:30 UTC
I assume David means more than 2GB ;)

Comment 11 Greg Kroah-Hartman 2005-08-04 13:07:59 UTC
Yeah, more than 2Gb :)
Comment 12 Marco Clocchiatti 2005-08-17 05:56:58 UTC
Solved upgrading bios to f4 version (see 
http://www.gigabyte.us/Motherboard/Support/BIOS/BIOS_GA-K8NF-9.htm). 
 
f7 version gives me another problem (may be a second bug?) 
 
Thank you for your support. You help me to understand a lot of things.
