FWIW, that BUG is not actually in the prism54pci code (but it may indeed be 
caused by prism54pci).  I'll have to investigate further to understand what is 

It looks like the last few instances are somewhere else entirely.  It is 
possible that something else is causing this problem.  Could you try to 
recreate it in some other manner (e.g. using a wired connection instead of 
wireless)?  It may be interesting to see if the problem disappears or just 
reinvents itself...thanks!

What kernel version are you using?  Can you reproduce this against 
the -107.fc8 kernel?

Email from "Matt Kohner" <mkohner@gmail.com>:

I installed -107 tonight. When trying to download several rpms after
rebooting into -107, I got a hard lockup, with just the capslock
indicator blinking.
I am unable to reproduce the kernel BUG error.
Before updating to -107, I usually got a hard lockup using the wifi
card. I would get a lock up with the capslock indicator blinking on
the keyboard. Only twice did I see the kernel bug actually logged, and
in those cases, the system did not lock up.
I was unable to reproduce either error using the ethernet adapter.
Just the wireless card causes the lockups.
Comment 5 Matthew Kohner 2008-02-09 09:31:15 EST
Updated to kernel. Lockup still occurs. 
Comment 6 John W. Linville 2008-04-02 10:22:08 EDT
There was a recent prism54 patch that _might_ relate to this problem.  Could 
you try this kernel?


Does that resolve the issue?
Comment 7 Matthew Kohner 2008-04-05 09:59:56 EDT
Updated to kernel- - lockup still occurs. 
Comment 8 John W. Linville 2008-11-12 09:44:05 EST
Wow, long time...are you still seeing this issue with current kernels?  I've never seen anything like it reported anywhere else.

This message is a reminder that Fedora 8 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 8.  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bug reports from releases that are no longer maintained.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 '8'.

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 8'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 8 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 10 Bug Zapper 2009-01-09 02:33:59 EST
Fedora 8 changed to end-of-life (EOL) status on 2009-01-07. Fedora 8 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.
