Re: "Kernel panic: VRKADINT" under heavy I/O. It is really BRKADRINT from Adaptec source

[Jeff Johnson <jeff.johnson@wsm.com>]

Forgive my typo. The KP error was "Kernel panic: BRKADRINT" and is 
located in the Adaptec aic7xxx/aic79xx driver sources.

Now I just have to figure out why it is occurring. The motherboards have 
Adaptec 7902W onboard, attached to a separate PCI-X bus from the 
Infiniband HCA.

Apologies for the confusion
