 |
|
Hi,
I have a PPC Mac-mini running the latest stable Gnome & kernel.
I've noticed that once I play a video in smplayer, the CDROM drive starts acting bizarre.
I am not using the CDROM at all. Any video I play is from the hard-disk or network, yet after playing a video, the CDROM starts seeking periodically.
What I mean is there is a seek, which I can only deduce is from the CDROM because it sounds like the CDROM is trying to access a disk. I suppose it *could* be the internal hard-drive, but this is too loud for it to be the hard-drive.
Anyway, the CD will attempt to seek or whatever, then fall silent for 5-10 seconds, then it will do it again. This goes on for hours until I reboot.
Once rebooted, it is quiet for hours or days if I don't play any videos. But once I do, it starts the pattern again.
I've checked to see if there is a zombie in memory after I quit smplayer, but there are no unaccounted-for tasks in the process list.
Does anyone have any insight on this? For example maybe a command I could send to reset the drive without having to reboot.
I've checked both dmesg and /var/log/messages for any hints that something might be wrong but haven't found anything.
Thanks. |

Ubuntu's udev has a patch, builtin-block-polling.patch:
| Quote: | | Description: Set default polling interval on CD drives as well. The events_dfl_poll_msecs will not trigger if "block" is not a module, but built in. This will avoid udisks etc. having to poll from userspace, and provide proper ejection when the hardware eject button is pressed. |
| Code: | | ACTION=="add", ATTR{removable}=="1", ATTR{events_poll_msecs}=="-1", ATTR{events_poll_msecs}="2000" |
