Hmm - I wonder if this has happened to me a couple of times over the
past 24 hours.

1) Last night, sendmail refused to run, dropping 19 pieces of mail
along the way. It couldn't load a shared library (libdb.so, I
think) - running file(1) on the lib returned "data" instead of
the expected "ELF 32-bit LSB dynamic ..." I do run a weekly
tape-backup saturday night, so disk and cache systems had probably
been pretty busy during the night. After a reboot, things
returned to normal, so it must have been a corruption in memory.

2) My first attempt at booting up pre-2.0#6 halted when the kernel
was being uncompressed - "CRC error". This has never happened before.

That kind of errors give me the creeps...
