Description Mike Smith 2011-10-16 23:59:51 UTC

Description of problem:
System freezes completely a couple seconds after selecting "Safely Remove Drive" for an external Western Digital 1.0TB USB harddisk.

Version-Release number of selected component (if applicable):
Linux kernel 2.6.35.14-97.fc14x86_64

How reproducible:
Easy. Reproducible. Consistent.


Steps to Reproduce:
1. Run Fedora 14 w/updates & w/kernel 2.6.35.14-97.fc14x86_64
2. Plug in USB cable for 1.0TB Western Digital external harddisk
3. Use the drive: read/write
4. Right-click and select "Safely Remove Drive"
  
Actual results:
System freezes after a couple seconds. Appears to be a hard freeze - forced power off required to recover. Can't SSH into system. Can't ping system. Cntl-Alt-Del does nothing.


Expected results:
No system freeze + harddisk turns off.

Additional info:
Same steps always worked a-ok until approx. 6 weeks ago.  Now - it can be reproduced at will. Suspecting upgrade to a newer kernel might be the culprit.
Same steps with 32GB USB flashdrive and similar devices always works a-ok.
No related messages written to /var/log/messages.

Comment 1 Dave Jones 2011-10-19 17:51:38 UTC

At this point in F14's lifecycle, your best bet is to try to reproduce this on f15/f16beta (using the livecd).  We're not rebasing F14 given the limited time remaining until EOL, so knowing if this affects newer releases would be good to know, so we can try and get it fixed there.

I could not recreate this problem using the F15 livecd

Comment 3 Fedora End Of Life 2012-08-16 13:52:38 UTC

This message is a notice that Fedora 14 is now at end of life. Fedora 
has stopped maintaining and issuing updates for Fedora 14. It is 
Fedora's policy to close all bug reports from releases that are no 
longer maintained.  At this time, all open bugs with a Fedora 'version'
of '14' have been closed as WONTFIX.

(Please note: Our normal process is to give advanced warning of this 
occurring, but we forgot to do that. A thousand apologies.)

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, feel free to reopen 
this bug and simply change the 'version' to a later Fedora version.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we were unable to fix it before Fedora 14 reached 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, you are encouraged to click on 
"Clone This Bug" (top right of this page) and open it against that 
version of Fedora.

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:
