The /etc/daily script's nightly run uncovered an alarming fact. Since
I upgraded my kernel two days ago, files have started to become
corrupted at random. The modification date and size are unchanged,
but the contents are overwritten with random data at random points in
the file. The data that's appearing is from a web browsing session
from earlier today (I can see fragments of HTTP commands, addresses,
etc.). This has never happened before (I've been running NetBSD HEAD
sources on this machine since last August), so while it's possible
it's caused by some other change, the co-incidence seems suspicious.
(Though I should also note, I hadn't upgraded the kernel between May
17th and June 11th. Something's gone awry within that window.)

For example, in /usr/share/locale:

$ ls fi*
fi:
LC_MESSAGES

fi_FI.ISO8859-1:
LC_CTYPE        LC_MESSAGES     LC_MONETARY     LC_NUMERIC      LC_TIME

fi_FI.ISO8859-15:
colorls: 8%26radio%3Dtoronto%26news%3Dtoronto%26tv%3Dtoronto%2: Invalid argument

fi_FI.UTF-8:
LC_CTYPE        LC_MESSAGES     LC_MONETARY     LC_NUMERIC      LC_TIME

Should be:

$ ls fi*
fi:
LC_MESSAGES

fi_FI.ISO8859-1:
LC_CTYPE        LC_MESSAGES     LC_MONETARY     LC_NUMERIC      LC_TIME

fi_FI.ISO8859-15:
LC_CTYPE        LC_MESSAGES     LC_MONETARY     LC_NUMERIC      LC_TIME

fi_FI.UTF-8:
LC_CTYPE        LC_MESSAGES     LC_MONETARY     LC_NUMERIC      LC_TIME

I've reverted the recent smsc changes from my kernel to see if that
fixes things.
