Description Alexandre Oliva 2008-10-01 06:34:46 EDT
There's something wrong with the USB BIOS (?) of this notebook, that has always caused Linux to freeze when ohci-hcd is initialized before ehci-hcd, if there's any USB (2.0?) device connected (say, an external HD holding a mirror of the root filesystem, or even a simple mouse)

I've always been able to work around this problem by forcing ehci-hcd to be loaded before ohci-hcd, with modprobe.conf magic.

Obviously, this doesn't work when ohci-hcd and ehci-hcd are built-in.  ohci-hcd is always initialized first, freezing the system.

Actually...  The system doesn't freeze completely: it appears to hang for a while (15-60 seconds), and then continue booting up.  I guess I'd never waited that long before, when [oe]hci-hcd were modules...

Since it doesn't really freeze, this is not critical, but it might generate bug-reporting noise, in that people may think the machine actually froze.

This bug appears to have been reported against 'rawhide' during the Fedora 10 development cycle.
Changing version to '10'.

More information and reason for this action is here:
Comment 2 Bug Zapper 2009-11-18 03:27:19 EST
This message is a reminder that Fedora 10 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 10.  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bug reports from releases that are no longer maintained.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 '10'.

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 10'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 10 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 Bug Zapper 2009-12-18 01:28:09 EST
Fedora 10 changed to end-of-life (EOL) status on 2009-12-17. Fedora 10 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.
