Hello,

after the upgrade of the kernel, I cannot mount xfs filesystems any more.

I get this error:
mount: Operation not supported

/var/log/messages tells me:
Nov  6 12:48:19 grid-se118 kernel: Filesystem "cciss/c1d0p1": Disabling barriers, not supported by the underlying device
Nov  6 12:48:19 grid-se118 kernel: XFS mounting filesystem cciss/c1d0p1
Nov  6 12:48:19 grid-se118 kernel: SELinux: (dev cciss/c1d0p1, type xfs) has no security xattr handler

I installed these packages:
kernel-devel-2.6.18-164.6.1.el5.x86_64.rpm
kernel-2.6.18-164.6.1.el5.x86_64.rpm
kernel-headers-2.6.18-164.6.1.el5.x86_64.rpm
kernel-module-xfs-2.6.18-164.6.1.el5-0.4-2.sl5.x86_64.rpm

The problem disappears if I downgrading to the old kernel 2.6.18-128.7.1.

Best regards,
  Andreas
