Comment 3 Christopher Brown 2008-02-14 00:25:11 UTC

Hello,

I'm reviewing this bug as part of the kernel bug triage project, an attempt to
isolate current bugs in the Fedora kernel.

http://fedoraproject.org/wiki/KernelBugTriage

I am CC'ing myself to this bug and will try and assist you in resolving it if I can.

There hasn't been much activity on this bug for a while. Could you tell me if
you are still having problems with the latest kernel?

If the problem no longer exists then please close this bug or I'll do so in a
few weeks if there is no additional information lodged.

Comment 4 Robert Weiler 2008-02-14 15:38:25 UTC

I reverted to FC6,  2.6.22.14-72.fc6 #1 SMP, which does not have this problem.
I'm guessing it is because it doesn't use the unified disk interface. I need to
reinstall FC8 and apply updates to see if the problem still exists. I will try
to do that within th enext couple of weeks.

Comment 5 Christopher Brown 2008-02-14 23:02:13 UTC

Hi Robert,

Thanks for the feedback. If you would be so good as to test with F9 Alpha:

http://fedoraproject.org/get-prerelease

prior to the F8 re-install it would be greatly appreciated. In this way we can
resolve this issue prior to F9 release if able.

I'm re-assigning to the relevant maintainer as well.

Comment 6 Alan Cox 2008-03-10 12:04:32 UTC

This is another one which may need libata.dma=1 as we've got assorted lite on
traces now which seem to blow up when fed some commands by DMA

Comment 7 Robert Weiler 2008-03-14 02:15:45 UTC

I tried adding libata.dma=1 to my grub.conf file, but apparently the
2.6.24.3-12.fc8 kernel doesn't accept it. Can I do this by putting an hdparm -d
someplace in my startup scripts, or is there a better way?

Comment 9 Robert Weiler 2008-03-15 15:36:02 UTC

adding 
options libata dma=1 
to /etc/modprobe.conf seems to have fixed the problem. The machine has been
running overnight without problems.

Comment 10 Robert Weiler 2008-03-19 04:36:02 UTC

more info - while adding options libata dma=1 seems to have fixed the problem
running the x86_64 kernel, the problem is still occurring running a 32 bit
kernel 2.6.24.3-34.fc8 #1 SMP. dmesg shows some errors like this:

Comment 11 Bug Zapper 2008-11-26 08:40:17 UTC

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bug reports from releases that are no longer maintained.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: 
http://fedoraproject.org/wiki/BugZappers/HouseKeeping

Comment 12 Bug Zapper 2009-01-09 07:28:38 UTC

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.
