Description Warren Togami 2006-09-20 20:23:49 UTC
kernel-2.6.17-2.6.17-17-1.2647.fc6

During rawhide install with the above kernel on a VIA Nehemiah with USB hard
drive, the USB hiccuped and spat out the following in dmesg.  It seems to
recover from this problem and continue the installation.

More of the dmesg leading up to this, which unfortunately doesn't go back far enough.

Comment 2 Pete Zaitcev 2006-09-20 23:31:05 UTC
Aww, man. I am not surprised usb-storage triggers it, it's not natural
for HBAs to process on threads. But I have no idea how to add lockdep
annotations...

Comment 3 Dave Jones 2007-04-23 18:53:38 UTC
Is this still happening? If so, Pete shall we kick it upstream ?


Comment 4 Bug Zapper 2008-04-03 18:16:25 UTC
Based on the date this bug was created, it appears to have been reported
against rawhide during the development of a Fedora release that is no
longer maintained. In order to refocus our efforts as a project we are
flagging all of the open bugs for releases which are no longer
maintained. If this bug remains in NEEDINFO thirty (30) days from now,
we will automatically close it.

If you can reproduce this bug in a maintained Fedora version (7, 8, or
rawhide), please change this bug to the respective version and change
the status to ASSIGNED. (If you're unable to change the bug's version
or status, add a comment to the bug and someone will change it for you.)

Thanks for your help, and we apologize again that we haven't handled
these issues to this point.

The process we're following is outlined here:
http://fedoraproject.org/wiki/BugZappers/F9CleanUp

We will be following the process here:
http://fedoraproject.org/wiki/BugZappers/HouseKeeping to ensure this
doesn't happen again.

Comment 5 Bug Zapper 2008-05-07 00:51:55 UTC
This bug has been in NEEDINFO for more than 30 days since feedback was
first requested. As a result we are closing it.

If you can reproduce this bug in the future against a maintained Fedora
version please feel free to reopen it against that version.
