Description e.mergl 2008-05-25 10:52:51 UTC
Description of problem:

I'm running F9 on an Asus M3N-H using onboard grahics (GeForce 8300) and onboard
sound (hda_intel). 
The problem is a mouse freeze that occurs immediately when moving the mouse.
Unplugging and plugging in the mouse again doesn't help. 
A closer investigation showed, that this freeze happens only if the usb
controller shares it's interrupt with another driver:

lsusb:

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 002: ID 046d:c048 Logitech, Inc. 

cat /proc/interrupts

no freeze:

 20:      ohci_hcd:usb4                           <----
 21:      ohci_hcd:usb3, nvidia
 22:      ehci_hcd:usb2, eth0
 23:      ehci_hcd:usb1, ahci

freeze:

 20:      ohci_hcd:usb4, nvidia                   <----
 21:      ohci_hcd:usb3, HDA Intel
 22:      ehci_hcd:usb2, eth0
 23:      ehci_hcd:usb1, ahci

freeze:

 20:      ohci_hcd:usb4, HDA Intel                <----
 21:      ohci_hcd:usb3, nvidia
 22:      ehci_hcd:usb2, eth0
 23:      ehci_hcd:usb1, ahci

These configurations are dependend whether some onboard devices are enabled or
disabled in the BIOS setup. 
The configuration "no freeze" is only possible when disabling onboard sound
completely :-(


From this I deduce that the ohci_hcd module has a problem with sharing interrupts.

I have Linux 2.6.25.6-55.fc9.i686 #1 SMP Tue Jun 10 16:27:49 EDT 2008 i686 i686
i386 GNU/Linux

and the kernel freeze usually happens when a fly-over/popup help message appears
from the panel (KDE 3.5)

I can clear the freeze if I briefly unplug the flash memory stick

or sometimes ctrl-alt-delete (the old MS trick)

On boot I get several messages :

cannot enumerate hub 1-0:1.0

I have a card for USB 2.0 and the mouse uses a port on this card as does a flash
memory stick.

Never before have I encountered a kernel freeze with Linux!

Sounds like old MS days!

This started with 2.6.25 in F9

Comment 2 Bug Zapper 2009-06-10 01:09:36 UTC
This message is a reminder that Fedora 9 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 9.  It is Fedora's policy to close all
bug reports from releases that are no longer maintained.  At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '9'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 9's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 9 is end of life.  If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora please change the 'version' of this 
bug to the applicable version.  If you are unable to change the version, 
please add a comment here and someone will do it for you.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here:

Comment 3 e.mergl 2009-06-10 13:10:02 UTC
this bug is with all kernels of Fedora 10, with one exception: the bug does not show up with 2.6.27.24-170.2.68.fc10.i686.PAE.

Comment 4 Bug Zapper 2009-07-14 15:48:06 UTC
Fedora 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 is 
no longer maintained, which means that it will not receive any further 
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of 
Fedora please feel free to reopen this bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.
