system pauses, related perhaps to CD-ROM


My system is experiencing pauses of 5-10seconds every 30 to 50 seconds. Nothing is updated graphically, although keyboard input is still accepted. The system monitor shows no spikes of long duration in CPU activity.

I'm not a good sysadmin, but I do know to look to dmesg, and it shows some relevant info, which I've highlighted below. I left all the other junk because I didn't trust myself to separate the wheat from the chaff.

I should say explicitly that /dev/hdc and /dev/hdd are IDE ROM drives, hdc being a DVD-ROM and hdd being a DVD-R/RW.

My comments in italics:
Code:
.... [cut out]
[fglrx] AGP enabled,  AgpCommand = 0x1f004301 (selected caps)
[fglrx] free  AGP = 54800384
[fglrx] max   AGP = 54800384
[fglrx] free  LFB = 115339264
[fglrx] max   LFB = 115339264
[fglrx] free  Inv = 0
[fglrx] max   Inv = 0
[fglrx] total Inv = 0
[fglrx] total TIM = 0
[fglrx] total FB  = 0
[fglrx] total AGP = 16384  <------ this all likely to be from startup

And so on, with new entries appearing every pause.

A quick Google Tour didn't turn any thing up, but I'm almost sure that someone here has had similar experience. I'll keep looking, and hope that someone here might be able to help me better.

Thanks!

It's definitely CD-ROM related.

I couldn't unmount or open the hdd drive, so I rebooted and opened the drive. Therein was a DVD+R of digital photographs I'd laid in the drive. Now that the system is back up, no more pauses.

So no problem to solve, except my curiosity. What's the problem here? I can understand that the filesystem may be unreadable for Debian. I burned it under Windows with Nero without paying much heed to compatibility. But why should the system behave this way? If it can't read after trying once or twice, shouldn't it produce a notification instead of mysteriously causing practically the whole system to constantly pause?

If I had a gripe list, this would go on it.
