Description Alan Cox 2004-11-14 12:41:47 UTC

USB wasn't in use at this time. The bus has a pointless sony built in
memory stick thing but its never used.

FWIW, i think i'm seeing the same thing on a really old HP Omnibook
laptop with 2.6.9-1.724_FC3 (i686):

Comment 2 Dave Jones 2005-07-15 18:28:01 UTC

An update has been released for Fedora Core 3 (kernel-2.6.12-1.1372_FC3) which
may contain a fix for your problem.   Please update to this new kernel, and
report whether or not it fixes your problem.

If you have updated to Fedora Core 4 since this bug was opened, and the problem
still occurs with the latest updates for that release, please change the version
field of this bug to 'fc4'.

Thank you.

Comment 3 Lonni J Friedman 2005-07-15 18:30:30 UTC

I hadn't seen this in quite a while (and i've since upgraded to FC4).  I don't
know whether my issue wasn't the same as this bug, or if a previous kernel had
resolved it.

Comment 4 Dave Jones 2005-10-03 00:50:39 UTC

This bug has been automatically closed as part of a mass update.
It had been in NEEDINFO state since July 2005.
If this bug still exists in current errata kernels, please reopen this bug.

There are a large number of inactive bugs in the database, and this is the only
way to purge them.

Thank you.
