"Kernel panic: VRKADINT" under heavy I/O. What is the source or location of VRKADINT

"Kernel panic: VRKADINT" under heavy I/O. What is the source or location of VRKADINT

[Jeff Johnson]

Greetings,

    I have several systems that will hang under heavy i/o. This usually 
occurs during a Pallas AllToAll test over Infiniband. Is anyone able to 
point me to where I can find VRKADINT or what general area of the kernel 
this is coming from? Everything runs fine otherwise. When I start the 
AllToAll across 32 machines and get 128 cores all talking to each other 
at once random machines will panic with the VRKADINT. I cannot seem to 
find this message anywhere in kernel source.

details:
arch   x86_64
kernel  2.6.5-7.193-smp (SuSE Ent9)
proc  2x dual core Opteron 275
ram 16GB

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

[Jeff Johnson]

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
