[Btrfs-users] btrfs: sdb1 checksum verify failed

[Gabor MICSKO]

Hi,

I've created an test enviroment for btrfs 0.11. The aim of the test is
to compare speed of btrfs to ext3, reiserfs, jfs, xfs, etc.

I've created an 70 GB partition for btrfs, created btrfs filesystem on
it, which is currently mounted under /data. I put the kernel source tree
of Linux 2.6.24 to the btrfs, make allyesconfig, and i've created the
following script:

while true; do make -j2; make mrproper; cp ../.config .; make oldconfig;
done;

After some hours of compiling i got the following messages:

[...]

I suppose these messages indicates some data integrity issues on the FS.
Is this an correct assumption?

Best Regards,
