Package: linux-image-2.6.18-2-686-bigmem
Version: 2.6.18-5
Severity: normal
The kernel crashes when trying to capture digital video from a
JVC GR-DVL9600 PAL DV camera connected to the built-in firewire port of a
Lenovo Thinkpad X60s. I tried to track this down maybe one month ago, and
it looked like a bug in the interrupt handling logic. Maybe the code breaks
on multi-processor systems?
How to repeat:
cat /dev/dv1394/0
(the process blocks, waiting for data)
start the DV stream from the camera (i.e., press play,
or switch to shooting mode) -> the Linux kernel hangs!
If needed, I can repeat this on the text console and make a screen dump
by digital camera. This is likely to be an upstream bug, because the
crash also occurs on a self-built 2.6.19.1. DV capture via the
lower-level interface /dev/raw1394 does work.

Version: 2.6.24-1
old ieee1394 has been replaced with newer firewire,
you'll need some experimental libraries.
anyway the shortcomings of this old stack are gone thus closing.
