The constant blinking activity is a SCSI command error.

The SCSI "cpu" doesn't know what to do and has gone offline hence your
errors.

If you shut down your system and restart, everything will be ok again.

You might want to TURN DOWN the data rate on the SCSI drive via the
controller's BIOS.

|Here we go again!  Just rebooted and tried to burn a CD.  It 
|failed - even 
|though I am using supermount, it failed to mount the CDROM so 
|it failed. I 
|then tried again AFTER mounting the CD that I wanted to copy.  
|No worky.  The 
|CDRW has a constant, blinking activity light and it is now 
|impossible to 
|remove the blank without rebooting.  Upon trying to burn it 
|again after 
|mounting the CD with the image I wanted to burn, I get this 
|message (in 
|gcombust):

|WRONG!  The CDRW did not change magically into a normal CDROM, 
|it is STILL a 
|CDRW.  Is this the way that linux normally handles CD-RWs?  I 
|have used linux 
|for several years now and only recently started in with 
|CD-RWs.  This is new 
|to me but I must say that there is something seriously wrong 
|here in the way 
|it is treating the drive, and the way it makes it impossible 
|to use or open 
|the drive after a failure to copy or burn a CD.  
|
|I start kpm to see if there is a process associated with the 
|drive that might 
|explain the neverending blinking activity light but I see 
|nothing obvious - 
|so I can't kill the damn thing.  I am stuck with having to 
|reboot yet again.
|
|Someone toss me a bone here please.
