Yes, I have an Ultra 2 (2x300, 2GB RAM) and an Ultra 1 (143MHz, 448MB
RAM) that can readily be locked up with what appears to be the I/O
issue.  In both cases, neither running the systems with a serial
console or graphical console reveals anything when they lock up
(even with the syslog daemon turned off).

For both systems, I've tried kernels built with gcc-3.4.5 and gcc-3.3.6
and the only possible difference is that it *seems* to take longer to
crash on the gcc-3.4.5 built kernels (but let me generate some data to
back that up).
