Hello list,
I am convinced that there is a bug in the CAM code that leads to I/O starvation.
I have already discussed this privately with some. I am now bringing this up to
the general audience to get more feedback.
My setup is that I have 1 RAID controller with 2 arrays connected to

while going through the xpt code (8.0 RELEASE), it seems to me that some

where one has 2+ controllers on the system with /dev/daXX attached to them

Hi Greg,
thank you for all the feedback. The "set remotebaud 1" thing in my previous
email was a typo, I usually enter 9600.

I am not using remote debugging, that's why I made a call to kldsyms (local

May be I should try over a serial console. The system wasn't crashed or in db

As for the question regarding where I got the addresses from,
I typed:

Could somebody tell me why I can't "list" the source code of this kld?
I built the module with COPTS=-g, it is loaded in the kernel and I run kgdb in

doesn't like it. However if I run kldsyms, it only loads acpi.k

I am trying to do asynchronous send/receive between a user process that I am

Beside that idea, what else would you
