Not just kernel bugs.  Random hardware bugs/hiccups, including those
caused by static discharges, cosmic rays, etc.  Repeat after me: PC
Hardware is Sh*t.

No ECC on disk cables or systme buses, no power fail interrupts to
stop DMA when the power drops, most machines don't have ECC memory,
etc., etc., etc.

The *only* solution is to be super paranoid, do lots of checks, do
lots of backups, and do lots of checksums.  That is, if you care about
your data.  If the cost of reconstructing the data isn't very high, of
course, then don't bother.
