I also tried 2.6.12-rc6. Actually the problem is more severe in
rc-kernels, than in stable kernels. I do hope current rc6 defenetly
won't be the official 2.6.12
In 2.6.11.11 and in 2.6.11.12, the ps/2-keyboard and serial-mouse
doesn't get dead when pwc driver fails. In rc5 and in rc6 kernels they
do.
It's all in the bug thread
< http://bugzilla.kernel.org/show_bug.cgi?id=4510 >,
but seems like pwc driver cannot be unloaded from the kernel as long as
snd_usb_audio is in use. After I kill mixer_applet2 (which is Volume
Control gauge in GNOME Panel), the pwc driver gets restarted by khubd.
In rc-kernels, killing the mixer_applet2 also makes a Oops crash.
There seeem to be at least 3 separate problems, which are related.
May be, the first problem is insufficient power for the Quickcam, but
it then triggers few software bugs.
greg told, the keyboard + mouse problem would be fixed in stable
kernels, so I guess there was a bug then. I wonder why rc-kernels have
it unfixed.

OK, could try that also, but seems like the keyboard+mouse problem is
now fixed in stable kernels.
They said, I should ask you about the pwc-error codecs dmesg-log gets
before the pwc driver fails. Could it be just because either the usb bus or
cpu is too slow? Lots of buffer overrun-errors. (-63).
