|Whats your kernel version there?

I've tried on 2.6.9+Gentoo patches. I will try 2.6.11.6 in a couple of days 
(more on this below)

|And what does "dies" mean in this context - kernel panic?  Or just the I/O
|errors?  Can you give more details of these I/O errors too - are they being
|reported by the kernel or by rsync?

both the kernel (dmesg) and rsync (stderr) reported I/O errors. No IMMEDIATE 
kernel panic, but the kernel did panic after I attempted to remount the fs. 
Each subsequent time the server would reboot it would hang when attempting to 
mount the xfs filesystem - but no panic

|| This prompted me to unmount and run xfs_check which reported a journal
|| needed to be commited

|That should never happen after a clean unmount... do you see the same issues
|with a non-patched kernel.org kernel?  You using a non-patched gcc there?

The gcc is patched (I'm not sure that I know of any distro that used vanilla 
gcc... That said here is my idea:

I'm in the middle of spinning up a couple of release discs over the next 
couple of days - once this is complete I will try reverting the filespace to 
the xfs system. Are there any special flags I should use with mkfs.xfs ?
