A week ago, we discussed that diff under 2.2-alpha has some I/O problem.
Now I experienced "cat" I/O problem. I wonder if this is 2.2-Alpha I/O
problem or it is the Pentinum Pro problem since the "cat" I/O error
happened only on TYAN-S1662 Pentinum Pro machine. Here is the kdump:
# ktrace cat ~jin/hosts >> /etc/hosts
