Your hard drive is dying.  This may have caused the panic as a
secondary effect after the read failed.


Thanks for taking the time to respond.  Not good news obviously, but could
be worse.  This is my mule machine. I was using it as a gateway, to develop
some networking skills, and had installed SAMBA and was also trying to
install HylaFAX .  Fortunately it has a second hard drive which currently
holds the /var slice.  Out with the bad and in with the good.

BTW, can the data on this drive be copied to the surviving drive?  What
commands do I need to review?  My initial thoughts were to simply install
6.0 and go on from there.  Any hints/suggestions are appreciated.
