Re: 2.6.11: USB broken on nforce4, ipv6 still broken, centrino speedstep even more broken than in 2.6.10

  1. I don't trust ACPI
  2. my battery runs out quicker with ACPI compared to cpufreq

I _really_ _really_ don't want ACPI.  No, really not.  This is no idle
decision.  My current notebook is the only hardware I have ever seen
enabling ACPI not completely break Linux.  Of all my 10+ machines,
including my other 3 ones that are actually in use.

Which ACPI way to you mean, by the way?  Just enabling ACPI with thermal
and CPU or the cpufreq ACPI driver?  I think I tried that driver and did
not get the /sys interface to switch frequencies and governors.  If I
must, I can try again with 2.6.11, but I really really really do not
want to use ACPI, unless someone with a big shotgun is standing behind
me.

This kernel is stock 2.6.11 with CONFIG_USB_DEBUG=y.

When I put in my USB hub with my USB webcam, I get this:

(the line with Mfr=0 looks wrong to me).

on the mainboard), I get:

Now the webcam gets power (the light is on) but lsusb does not show it
and the device is suddenly only full speed, not high speed.
