FC2 Test 1: updatedb goes into uninterruptible sleep on /sys/class/tty/rfcomm49



System: FC2 Test 1. new install on formatted /, /var etc, but /home kept
from redhat 9 install.

Problem: updatedb is run from an nightly, but goes into an uninterruptible
sleep when trying to getdents64 on /sys/class/tty/rfcomm49.

[root zx root]# ps aux | grep updatedb

Leaking load average and processes at the rate of 1 per night would
obviously cause confusion for a lot of users.
