i've got some problems with iwi in Freebsd 8.0, using GENERIC kernel
everything works just fine, compiling a custom kernel, just excluding
some modules i don't need, cause an interrupt storm to happen on irq11:
Dec 22 22:35:18 legend kernel: iwi0: <Intel(R) PRO/Wireless 2200BG> mem
0xb0101000-0xb0101fff irq 10 at device 4.0 on pci6
Dec 22 22:35:18 legend kernel: iwi0: [ITHREAD]
Dec 22 22:35:22 legend kernel: wlan0: Ethernet address: xx:xx:xx:xx:xx:xx
Dec 22 22:35:32 legend kernel: interrupt storm detected on "irq11:";
throttling interrupt source
Dec 22 22:35:33 legend kernel: iwi0: timeout waiting for iwi_bss
firmware initialization to complete
Dec 22 22:35:33 legend kernel: iwi0: could not load boot firmware iwi_bss
maybe these other info from dmesg could be of some help to track down
the problem:

i did read somewhere in the forums/mls that a patch was on STABLE to
solve a interrupt storm related to PCI: could it be related to this?
is there a patch i can apply to get rid of this problem?
(i've tried to compile kernel with/without optimizations which you will
find commented out in the configuration attached to the mail, obtaining
always the same interrupt storm problem.)
thanks
regards
ocean
