I just had a bunch of kernel panics over the weekend.  In my case it
seems to be hardware related .. but in the process of diagnosing that
I ended up with quite a few blown up mysql tables.  I found this in
the MySQL reference manual:

Short summary:
backup your data tables!
(from a console)
cd to the directory with your mythtv tables
check for troubled tables with
  $ myisamchk *.MYI
fix troubles tables with (quick repair)
  $ myisamchk -r -q <tablename>
if that does not work, it should tell you what you need to do to fix
them, in my case it was removing the 'quick' option
  $ myisamchk -r <tablename>

There are some other options in the linked page above, but those three
commands served my needs.  Good luck!
