[ivtv-users] unable to handle kernel paging request

[Scott Reynolds]

I don't mean to sound like a "me too", but I've just run into the same
problem. It has happened twice this week; but prior to the paging request
error, I was getting kernel PREEMPTs that caused MythTV to hang up. I seem
to recall that ivtv isn't really happy with preemption, so I compiled a new
kernel and thought I was in the clear.

Prior to this issue my system has been stable for a long time now. The
problems started when I installed a new HVR-1600 in preparation for the DTV
change in the US. I am using a PVR-150, a PVR-350 using TV out, and now the
HVR-1600. At least at this point, anyway, the problem has only occurred for
me while I'm pushing an MPEG stream (captured on one of the first two cards)
out through the PVR-350.

Some possible problems that I've eliminated include whether it is a local
APIC or ACPI problem. My machine doesn't want either enabled; the problem
is especially catastrophic if I have "acpi=force" in the boot arguments.

I'm sorry I can't provide much more than that at the moment. I will also be
unavailable to test any changes for at least a few days, sorry. I do hope
this additional info helps, though.
