Do you have a link to any info on that issue? Does it only affect RedHat, or does it also affect distros running new kernels? I am using ext4 rather than xfs because I was reliably able to make machines running xfs lock up (these are Ubuntu not RedHat BTW) just by throwing bonnie++ load at them, but not when running the same test on ext4.
