Yes

That's what led me into try to figure out where it gets the firmware
from in my first mail.

Ok, thanks, I tried. Actually I tried setting it to both 10 and 100 just
in case. But no luck.
Replay of the attempt below, it seems that it makes no difference if
if_iwi or iwi_bss is loaded first. Also, setting debug.iwi=1 seems
only to add the iwi_newstate lines. I tried to set it to 2 to see if
that would produce more output but no. (the complete dmesg after boot is
at the end of the mail).

... gave up. The above was with a custom kernel where I removed
everything that did not seem necessary, keeping "device firmware" and
"device wlan". I have just tried also with a GENERIC kernel and there is
no difference at all.
Trying to load/unload too many times can cause the system to crash hard
- no nice page fault or kernel trap or anything, just a hard reboot. In
/var/log/messages I found this:

crash. So, something is happening, the if_iwi seems to do what it can. I
keep thinking that a conflict in the devices irq or other parameters may
cause it to fail, the irq storm when the interface is first brought up
seems to indicate such conflict.
Any ideas how to test this? Are there any things that I can do to shed
more light on the hardware/device config?
Thanks, Erik
