logs full of chatty IDE cdrom

Hi,
I'm not sure but this seems to be a lot worse in 2.5.x for some
reason; my logs are full of I/O errors, not ready's and other errors from my CDROM drive that is playing audio CDs; I suspect at least some of it is due to kscd trying to figure out if there is a CD in an empty drive.

Is there any way to selectively silence errors from one IDE device? It would make it easier to spot real/important errors from hard drives and the like.

That shouldnt be generating messages. Its more important to know why or to see wtf its doing that generates them

Are you running with a Welsh locale there?

OK, the full messages on starting kscd up are:

That is with no disc in the drive; the drive identifies itself as:
'Pioneer DVD-ROM ATAPIModel DVD-116 0109' and driver is 'ide-cdrom version 4.59-ac1' (in 2.5.69)

But to be honest, my observation is more general - I'm sure I've seen similar messages from VMware on systems (this system does not have it) and other things rattling the CD drive on older kernels. In general I think I'd just like to tell IDE to be quiet about certain drives so it makes it easier to spot serious errors in the logs.

Ydw.

That is interesting. Someone sent a SCSI command the it really didn't like. This isn't a dell 8100 or similar laptop is it btw ?

I guess people with raw drive access should learn to program as well. You could play with drive->quiet I guess (I think its drive->quiet) but right now the IDE layer has no notion of how severe an error is although it has some idea who caused it. For 2.5.x passing quiet/loud in the taskfile is a viable extension for 2.4 its not so clear how you would do it nicely.

Nope, thats just a standard DVD; its plugged into one channel of a Promise Ultra100 TX2; an Iomega Zip 100 is a slave on the same channel. Everything works fine - the only problem is the log messages from audio playing. /proc/ide/hde/settings is:

using_dma               0               0               1 rw

My full set of IDE stuff is:

On board AMD 766 ViperPlus IDE:
hda - IBM Deathstar 60GB
hdc - Memorex CD-RW with ide-scsi

Promise Ultra100 TX2
hde - the offending DVD ROM
hdf - Iomega ZIP 100 ATAPI
hdg - IBM Deathstar 60GB

I guess I was really after a /proc/ide/hd?/verbosity to shut the drive up independent of what application was trying to talk to it.

I have a Toshiba DVD drive, that while quiet in 2.4, generates 3-4 messages just during kernel start and initial module loading .. I can forward it if need be.

This should fix it.
