In the meantime I've tried the three possible drivers (XP, NT and an
unlabelled one). I've also installed a recent 8-current snapshot,
updated to latest source and built world, and tried the XP driver. Still
get interrupt storms everywhere, also a panic (I think) in 8-current.
Should I give up or are there other things to try?
Panic should not happen. Please provide backtrace(or crashdump or textdump)
`fetch http://www.fishercroft.plus.com/vmcore.1.gz' should get a
crashdump from a non-debug kernel, see below. It's about 17mb
I built a driver with the XP driver using ndisgen and the same source as
my recent build world.
I kldload the driver module which also loads ndis.ko and if_ndis.ko.
in rc.conf and I get ndis0 and wlan0 created when I plug in the card.
The interrupt storm starts when I do
# ifconfig wlan0 <ip addr>
The panic occurs maybe a minute or two after the ifconfig.
I got a panic but I couldn't get a crashdump with the GENERIC kernel
(nothing relevant to dumpon or savecore happened at all, no boot
messages, nothing in /var/crash).
I did get a bunch of stuff on ttyv0, I can post a photo somewhere if
required. Or is there a way to get the screen output in text format?
I built a kernel with the following changes
#makeoptions DEBUG=-g # Build kernel with gdb(1) debug
#options KDB # Enable kernel debugger support.
#options DDB # Support DDB.
#options GDB # Support remote GDB.
#options INVARIANTS # Enable calls of extra sanity
#options INVARIANT_SUPPORT # Extra sanity checks of
internal structures, required by INVARIANTS
#options WITNESS # Enable checks to detect
deadlocks and cycles
#options WITNESS_SKIPSPIN # Don't run witness on spinlocks
I got on ttyv0:
interrupt storm detected on "irq11:"; throttling interrupt source
repeated about 20 times then
Sleeping thread (tid 100084, pid 0) owns a non-sleepable lock
panic: sleeping thread
cpuid = 0
Physical memory: 434 MB
Dumping 79 MB: 64 48 32 16
(The above typed by hand)
Let me know if there is more I can do but (caveat) I'm not a developer
and I only put CURRENT on the machine to test if the problem had been
fixed, ie please don't flame me if you ask me really difficult stuff and
I don't understand it :)
