doing a test run for bonnie on an 100M file, after a ton of `attempt
to access beyond end of device' came a BUG:

I think the log was also corrupted by this bug becouse I can't
explain the strange messages logged by the kernel. (syslogd couldn't handle
the load ?).
egcs-2.91.66 19990314/Linux (egcs-1.1.2 release), kernel 2.3.8
(tested on 2.3.6 and 2.2.10 and bonnie run ok)
