"0-order allocation failed"

[tls@reefedge.com]

We're building a server for a CVS repository consisting of several tens
of thousands of files; about 1.5GB of data total.  It's a two-processor
Pentium-III machine with a Mylex RAID controller and 4GB of RAM.

We installed from the RH7.1/XFS 1.0.1 media, built a 2.4.5 kernel with
the XFS 1.0.1 patches, copied the repository into place and ran a small
script that copied the repository four times, copied the resulting directory,
then removed both copies.

I let it run overnight -- came in this morning to find that the first time
I ran any command that generated any disk I/O on the box, I got dozens of
"0 order alloc failed" messages on the console and then a hard hang.

I see mention of this bug in a list message from April, but nothing since
then.  Has it been fixed, or even analyzed?  If it's been fixed, is there a 
simple patch against 1.0.1 or will I need to run the latest from CVS?
