ADSL USB hotplugging breaks between kernel 2.6.6 and 2.6.7!?

ADSL USB hotplugging breaks between kernel 2.6.6 and 2.6.7 on system with legacy soundcard

Using fedora core 2 I can get either adsl hotplugging with a speedtouch 330 usb adsl modem working or X working but not both. In kernels 2.6.5-1 and 2.6.6-1 my laptop will freeze completely when I start X due to some conflict with my legacy oss driver on my laptop. I'm sure that it's the soundcard because during the fc2 installation when I test the soundcard the system immediately freezes.

My dell laptop has a neomagic corporation nm2200 magicmedia 256AV audio soundcard which uses the snd-nm256 module. The testing that I have done with fedora core 2 kernel rpms:
  • 2.6.5-1 adsl works; X hangs
  • 2.6.6-1 adsl works; X hangs
  • 2.6.7-1 adsl fails; X works - with sound
  • 2.6.8-1 adsl fails; X works - with sound

I can toggle back and forth between these kernels (586 and 686) without changing anything else on the system by using "rpm -U" and reliably get these results. So I can have internet or X but not both!

Note on mandrake 10 with 2.6.3-7 kernel adsl fails with the same error message and X works (I think with sound).

I don't know if it's co-incidence but maybe the fix?? for the legacy soundcard problem broke adsl usb hotplugging. I'm curious to know if other people using kernels 2.6.7 or 2.6.8 without legacy soundcards have this same issue will usb adsl modems or usb hotplugging in general?

The main error message I see is:

modem_run[2567]: Another program/driver is already accessing the modem (interface 1 cannot be claimed)...

When the modem works the firmware is successfully loaded with the light on the modem flashing - otherwise no firmware is loaded. Are there any known issues/bugs? Below are two sets of log files (when it works and when it doesn't).

In 2.6.6-1 log when it is successful:

well the answer (if anyone cares) was found on this page:
just add speedtch to the /etc/hotplug/blacklist

The X thing was some type of fish.
