Hi,

Yes, looks very simliar ...


some patches off the list [attached] fixed it. I expected these to be
in -rc2, I am not able to say which patch is missing.


Uhm, strange. The bttv patches _are_ merged.
Not sure about any for dvb-bt8xx, Michael?


Hm, I'm not sure either, because Eyal says that the problem does not exist with rc2-mm1. But AFAIK all DVB stuff has been merged by Linus so I'm clueless here... 8-(

I now managed to get the problem with rc2-mm1/2. They reaction is different
(I do not get a lockup) but the oops shows up. Here is one from rc2-mm2. The
system was still usable at this point.

I now think that the original problem I reported is not the same as this one
which happens with all kernels I tried.

Also, does anyone know how to switch to text console when X locks up (as
it does for me)? sysrq works but does not allow me to switch to another
console. Since the hard lock does not log the oops, and I cannot see the
text from sysrq, I cannot report the details.
