Description Eryu Guan 2011-03-18 06:19:26 UTC

Description of problem:
Got kernel panic when running xfstests 234 on ext4 with 2048 block size, tests were running on real block device instead of loop device

Version-Release number of selected component (if applicable):
kernel 2.6.32-122.el6.x86_64
quota 3.17-14.el6.x86_64

How reproducible:
reliable

Steps to Reproduce:
1. Prepare two partitions for testing
2. yum install rh-tests-kernel-filesystems-xfs-xfstests -y
   cd /mnt/tests/kernel/filesystems/xfs/xfstests
3. TEST_PARAM_TEST_DEV=/dev/sda5 TEST_PARAM_SCRATCH_DEV=/dev/sda6 TEST_PARAM_RUNTESTS=234 TEST_PARAM_FSTYPE=ext4 TEST_PARAM_BLKSIZE=2048 TEST_PARAM_LOOP=1  make run
   Replace sda5 and sda6 with correct ones
  
Actual results:

Comment 1 Eryu Guan 2011-03-18 06:21:09 UTC

I'll try to get a vmcore and on RHEL6 GA kernel to see if it's a regression or not

Comment 2 Eryu Guan 2011-03-18 06:25:36 UTC

I just notice it's already been reported as bug 680105 ... Close it as duplicate
Sorry for noise
