Actually, that's what you told me. :) I simply noticed that the

machine reliably freezes every time I power up my iBook with OS X.
kernel/5504: re(4) on ASUS V3-P5G965 Core 2 Duo ...

http://cvs.openbsd.org/cgi-bin/query-pr-wrapper?full=yes&numbers=5504
FWIW, I've also noticed that sftp'ing the machine from a Windows box

on the same local network can reliably freeze it, too. (Although

non-sftp ssh sessions never caused the machine to freeze.)
One other interesting point is that it appears that only one processor

would freeze (e.g. sometimes it is still possible to login from the

console and do a few things until the box is totally frozen).
FreeBSD 7.0 re(4) does not appear to be affected by this bug (insofar

as the machine doesn't freeze).
Cheers,

Constantine.
