SUMMARY: solaris kernel help

Thanks to:

Hendrik Visage
Buddy Lumpkin

Unfortunately I have to track down what patch actually caused the system to crash so I am doing an Initial Install. Note though that when upgrading it does remove a whole lot of patches but does not downgrade them (kept a copy of this list to monitor during the new install)

Thanks a million guys.
