Hello! I have some strange errors with burning a DVD. In the beginning of the burn-process, burncd stopps and writes the following output to /var/log/messages. Jul 27 23:21:36 master kernel: acd0: FAILURE - START_STOP timed out Jul 27 23:22:06 master kernel: acd0: TIMEOUT - READ_BIG retrying (2 retries left) Jul 27 23:22:36 master kernel: acd0: WARNING - READ_BIG interrupt was seen but timeout fired Jul 27 23:23:06 master kernel: acd0: WARNING - READ_BIG interrupt was seen but taskqueue stalled After the aborted burn-process, neither the system is accessible via ssh nor any other process do their normal job. (Even though some processes "seems" to work, e.g. ssh asks me about login/password but doesn't give me access to the machine.) Furthermore, it is not possible to manually eject the DVD by pressing the eject button or by using the "cdrontrol eject" command. Unfortenuately, a reboot helps. Due to the fact that the obove mentioned error occurs exactly once a week with the same DVD-media, I suppose that this media is the originator of the problem. But anyhow, shouldn't the system be in a stable mode, even if I use a bad media? And maybe someone can give me a hint what the kernel message means? Thanks for clearing that up!
