Description Han-Wen Nienhuys 2005-08-30 10:21:43 UTC 
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; nl-NL; rv:1.7.10) Gecko/20050720 Fedora/1.0.6-1.1.fc4 Firefox/1.0.6

Description of problem:

Hi,

for some reason my USB2 HD went offline during a backup. This produced
lots of

scsi0 (0:0): rejecting I/O to offline device
scsi0 (0:0): rejecting I/O to offline device
Buffer I/O error on device sda3, logical block 121

then I got an oops,

Unable to handle kernel NULL pointer dereference at virtual address 00000000

The call trace shows trouble in the HFS+ module; see kernel log for
more information. The disk is a toshiba 40gb 2.5" IDE in a Sitecom
enclosure. It's been formatted on a Mac with a HFS+ filesystem.

The system appeared stable but froze hard while trying to enter this bugreport.
I'm attaching the output of dmesg to this report.

Version-Release number of selected component (if applicable):
kernel-2.6.12-1.1398_FC4

How reproducible:
Couldn't Reproduce

Comment 3 Dave Jones 2005-09-30 06:58:16 UTC 
Mass update to all FC4 bugs:

An update has been released (2.6.13-1.1526_FC4) which rebases to a new upstream
kernel (2.6.13.2). As there were ~3500 changes upstream between this and the
previous kernel, it's possible your bug has been fixed already.

Please retest with this update, and update this bug if necessary.

Thanks.
Comment 4 Dave Jones 2005-11-10 20:04:25 UTC 
2.6.14-1.1637_FC4 has been released as an update for FC4.
Please retest with this update, as a large amount of code has been changed in
this release, which may have fixed your problem.

Thank you.
Comment 5 Han-Wen Nienhuys 2005-11-11 00:01:36 UTC 
Hi,

as the report says, this is a non-reprocible crash anyway, so let's close this
report for now.
Comment 6 Dave Jones 2005-11-11 06:15:23 UTC 
ok, thanks. 
feel free to reopen at any time (or file another bug) if it reoccurs.
