Description mal 2000-08-05 02:39:32 UTC 
As soon as Gnome started it starts polluting dmesg 
buffer.
Use any IDE workstation and while 
no CD is in CDROM you get a new message 

VFS: Disk change detected on device ide1(22,0)
VFS: Disk change detected on device ide1(22,0)
VFS: Disk change detected on device ide1(22,0)
VFS: Disk change detected on device ide1(22,0)

about every two seconds.
Use dmesg and you will see these messages.
When you put a CD to CDROM 
the message of above stops and you get

VFS: Disk change detected on device ide1(22,0)
ISO 9660 Extensions: Microsoft Joliet Level 1
ISO 9660 Extensions: RRIP_1991A

no dmesg buffer polluting any more.
The problem problem exists only when 
no CD is in the CDROM when GNOME is running.

use dmesg command to see messages of above.

This is magicdev. Turning it off is one cure (it just automounts cds in gnome).

I don't know of a way of fixing this within magicdev. See Bug #6006
for extensive commentary. (Until someone tells me a good reason for the
printk(), I would consider it a kernel misfeature that it is printing
out these messsages, leaving aside the misdetection of media changes.)
