{firewire,modem,superdrive}problems with 2.4.21-ben2

[Soeren Sonnenburg <debianppc-ml@nn7.de>]

Hi...

I still have trouble with the stuff in the subject on a 15" 1Ghz G4
Powerbook. The neat thing about it is that it is all reproducable.

Here we go:


1. firewire
 do:
	modprobe ieee1394
	modprobe ohci1394 (<- bang leaves me in xmon with a nice message
	Jul  9 12:26:05 no kernel: kernel BUG at sched.c:720!
	Jul  9 12:26:05 no kernel: kernel BUG at
	/usr/src/linux/include/asm/semaphore.h:84!)

leaving xmon twice returns me to the console and everything seems to be
fine again.

modprobing sbp2 then finds the attached drives and accessing it seems to
be ok, except that I my logs fill with stuff like:
...
Jul  9 15:08:52 no kernel: ieee1394: unsolicited response packet received - np
Jul  9 15:08:52 no kernel: ieee1394: contents: ffc09d20 ffc10000 00000000 0e945194
Jul  9 15:09:52 no kernel: ieee1394: unsolicited response packet received - np
Jul  9 15:09:52 no kernel: ieee1394: contents: ffc02520 ffc10000 00000000 db025194
...


2.modem
I use the latest hcfusb driver as from their website. The driver loads
ok and I can even use minicom dial up to some remote machine and the
like. However when using wvdial I get a successful connection again and
an IP assigned, but as soon as I ask about routing tables (route) or
ping to the gateway I land in xmon.

3.superdrive

when using dvdrecord or the patched cdrecord, it seems to dvd-burn ok,
but from time to time I get 
Jul  9 12:21:51 no kernel: hdc: timeout waiting                        
for dbdma command stop
Jul  9 12:21:51 no kernel: hdc: bad status at DMA end, dstat=8400

and the whole dvd-r is just garbage...

I will happily help tracing bugs when someone with in detail knowlege
tells me what to do.

So long,
Soeren.
