Subject: [Bug 10976] New: Soft lockup on (intentionally) corrupted filesystem
http://bugzilla.kernel.org/show_bug.cgi?id=10976
Summary: Soft lockup on (intentionally) corrupted filesystem
Product: File System
Version: 2.5
KernelVersion: 2.6.25.8 + patches for bug 10882 problems
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: ext3
AssignedTo: [email protected]
ReportedBy: [email protected]
Distribution: Debian sid (unstable)
Hardware Environment: qemu x86
Software Environment: Minimal Debian sid
Problem Description:
Mounting one of the attached intentionally corrupted ext3 filesystems and
accessing it causes a soft lockup. I believe they probably are the same bug
(both happen in __log_wait_for_space()), but the backtraces vary quite a bit so
I attach two test cases.
My kernel is 2.6.25.8 + three patches posted by Duane Griffin for #10882,
namely (I hope I understand the git terminology right, at least you can grep
lkml archives for these):
- 6ae4ecf..8019bf2
- 7712682..bc030f4
- 0b8cf80..ea0236b
Steps to reproduce:
1. bunzip2 one of the filesystem images
2. mount fs.img /mnt
3. ls /mnt
