Hi all,
I've just released ivtv-0.10.3. The main change is that PIO memory copies
are no longer done inside the interrupt handler: this led to a host of
subtle issues like clock drift, missing IR key presses, wrong reporting of
CPU usage and probably other issues as well. It is recommended to upgrade
to 0.10.3. This driver is for kernels 2.6.18, .19, .20 and .21.
Enjoy,
Hans
- Models 30012 to 30039 are for a low profile PVR250, not a PVR150.
- Move PIO memory copies from the interrupt handler to the work handler.
This fixes problems with the timer ticks and IR remotes.
Was this release supposed to address the
ivtv0: All encoder MPEG stream buffers are full. Dropping data.
ivtv0: Cause: the application is not reading fast enough.
issue? I have been running the 10.3 svn branch for a few days,
and I still seeing this occassionally, even though I have the following

Like others, I have both these cards in a box that has an
AMD x2 3800+ w/1GB of RAM. Now, I do have lots of disks in there
and I run [EMAIL PROTECTED], but FAH is running at nice 19 priority, so
that shouldn't be the problem.
Any thoughts on what else could be tweaked?
