You can't tell which card really interrupted. All of them are called.

as i said also before, my intentions were never to

In simple terms, what i am saying is, the people who

port JFS.
Then, i will count the votes,

It came up in a meeting today at Apple just how fragile the BSD NFS
implementation was before significant work was put in to stabilizing it,
and in that discussion came up a little test tool written originally by
Avie Tevanian and subsequently improved by one of the folks here.

There's a mention in the FBSD hacking guide that a detach() routine
for a device driver can forcably close all open descriptors for
its device before it unloads.
How does one do this?

The way the story goes, it wasn't until the last minute that the initial
PCI working group realised that they'd forgotten to do something about
interrupts, and so the gross hack that we're now stuck with was
implemented.
