Description Edouard Bourguignon 2006-08-29 13:09:57 UTC 
Description of problem:

Kernel oops and froze while using a mounted loop device

Version-Release number of selected component (if applicable):

kernel-xen-2.6.17-1.2174_FC5

How reproducible:

static

Steps to Reproduce:
1. mount -o loop hd.img /mnt
2. cp -a huge_data/* /mnt
  
Actual results:

Computer totaly frozen and need a hard reboot. Sometimes we can see what seems
to be a kernel oops just before the crash

Expected results:

copying files in the mounted loop device shouldn't hang the system

Additional info:

This occurs on a IBM x365 with 12GB of RAM, therefor we need the PAE support.
This bug doesn't occur if we boot with the noacpi parameter

Comment 2 Chris Lalancette 2008-02-26 23:18:11 UTC 
This report targets FC5, which is now end-of-life.

Please re-test against Fedora 7 or later, and if the issue persists, open a new bug.

Thanks
