Copying large files from USB hard drive to RAID 5,XFS array causes Soft Lockup on CPU

[swests]

Binary package hint: cpio

Using cpio -pvdm to copy lots of files from a USB drive to a RAID 5
array (XFS) causes this error.

Using Ubuntu server 8.10, release 8.10, fully patched.

AMD Quad core, 8GB, SATA-300 drives in mdadm managed array.

External drive is NTFS.

dmesg gives: BUG: soft lockup - CPU#1 stuck for 61s! [cpio:685]

I also see the same with cp so I suspect this is probably a kernel issue rather than cp or cpio.
