Now, I got some lockups. I can reproduce them(?), or at least the
symptoms by just SIGKILLing X.
But, it seems that I have no chance to debug this problem, as I have
no access to VC's after the lockup of X. Disk access is also not
working, so I suppose a locked PCI-Bus?? Sometimes videoplayback
stops, sometimes it continues... sort of weird.
I think it is _not_ a timeout, since then it should return control
back to me after a while. But definitly, bttv is triggering
something.
Q: What is the PCI-Bridge feature disabling of? (Yes, I have an FX)
Could it be still too less feature disabling?
Lockups (during normal usage of xawtv) happen usually at channel-switch
time.
Hope this helps. At the weekend I could get a second machine to test,
if networking locks up, too...
