We're running a mix of ext3 and xfs file systems on CentOS 4 workstations at our site. We have benefitted greatly from the increased performance and fast (crash recovery) reboot times that we get from xfs. We're currently running CentOS kernel 2.6.9-42.0.8.EL and xfs version 0.2-1.
We have one host where we've got issues. It's a (very) busy imap server with external scsi hardware raid, dual Xeon CPUs, and 8GB of RAM (it runs the hugemem kernel).
This implies that you are running i386 and not x86_64. It has been my experience that xfs is less that solid on c4.i386 but fine on c4.x86_64. This is most likely due to the fact that i386 uses 4k kernel stack while x86_64 uses 8k.
