Hi,
I was using dvd::rip to scan the volume level of a set of vob files
on a hard disc. The following dmesg is from the second time I tried
it. Progress got to about 20% (very quickly, I assume the file had
been cached), then finished. This turned up on the console:
Message from syslogd@atlas at Tue Sep 5 15:23:55 2006 ...
atlas kernel: Oops: 0000 [#4]
followed by registers and a call trace. Something very similar
happened when I tried to cat the file to /dev/null. After
repeating this a couple of times I cleared the cache by copying
another large file to /dev/null which seemed to eliminate the
problem.
The dmesg output is below. What I'd like to know is whether this
looks like a hardware problem, a filesystem problem or simply a
bug somewhere. Thanks for your time.
