Problemas con el snd_intel8x0 y el 2.6.29.6-213.fc11.i686.PAE

Desde la última actualización del sistema (Fedora 11 sobre un Thinkpad T43) comencé a tener problemas con el audio. Cualquier cosa que se conectara a pulseaudio a los 10 - 15 segundos dejaba de reproducir (casi colgaba la máquina con un 100% de uso CPU)

En la aplicación aparecía algo del estilo
$ totem Videos/big_buck_bunny_720p_stereo.ogg

Según lspci (es un Thinkpad T43)
00:1e.2 Multimedia audio controller: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) AC'97 Audio Controller (rev 03)


De momento a quedarse con el kernel-PAE-2.6.29.5-191.fc11.i686, con el que no tengo este tipo de problemas. En el Compaq 6510b (
00:1e.2 Multimedia audio controller: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) AC'97 Audio Controller (rev 03)
) no tengo el problema.

Alguien más por ahí con el mismo problema (no lo he pillado aún en bugzilla)

    I don't know where did you get the idea that some random blog is the best place to report bugs. Here's the bug entry, with a fix:

    https://bugzilla.redhat.com/show_bug.cgi?id=506075

    Hi:
    I'm not reporting a bug, I'm sharing an experience, and as you can see/read in the last parragraph I was asking if someone else has the same problem in order to get better information to report the bug. Also I was not being able to find the bug in bugzilla (same parragraph) thanks for the link.

    Regards

    I'm having the same problem, anyone have the kernel-2.6.30.4 x86_64?
    Please post a link to the rpm.

    thanks

    I had just posted a confirmation about the same problem. I think this happens only with the latest 2 kernels. I will investigate more and write in bugzilla.
