Summary: Infinite loop printing "__find_get_block_slow() failed."
on accessing intentionally corrupted ext4 fs
Product: File System
Version: 2.5
KernelVersion: 2.6.29-rc2 + the patches for #12430
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: ext4
AssignedTo: [email protected]
ReportedBy: [email protected]
Hardware Environment: qemu x86
Software Environment: Minimal Debian sid/unstable
Problem Description:
Accessing the attached intentionally corrupted ext4 filesystem causes a
seemingly infinite (at least _very_ long) loop where kernel floods dmesg with
these messages:
[ 67.126302] __find_get_block_slow() failed. block=4294967296, b_blocknr=0
[ 67.126609] b_state=0x00000020, b_size=1024
[ 67.126798] device blocksize: 1024
[ 67.126972] __find_get_block_slow() failed. block=4294967296, b_blocknr=0
[ 67.127244] b_state=0x00000020, b_size=1024
[ 67.127415] device blocksize: 1024
[ 67.127573] __find_get_block_slow() failed. block=4294967296, b_blocknr=0
[ 67.127844] b_state=0x00000020, b_size=1024
... ad infinitum
Steps to reproduce:
1. bunzip2 the attached filesystem image
2. mount hdb.153 /mnt -t ext4 -o loop,errors=continue
3. rm -rf /mnt >&/dev/null
