I gave 2.3.7-pre5 a (cautious) run today, and saw some file corruption.
For example, every time klogd starts at boot, I see corruption like that
in the extracted log data below. I have seen bits of C source and ascii
text in this spot. Mostly, logging works properly. If klogd hasn't done
anything in a (short) while, the next message logged will begin with data
from some unknown source. I saw similar corruption in a mailbox after
accidentally booting (oops) the wrong kernel and calling fetchmail before
realizing I had turned it loose on a live fs. Fsck found nothing wrong.
This is gcc-2.7.2.3 compiled virgin 2.3.7-pre5 source.
