Description Need Real Name 2003-02-09 11:58:10 UTC

I get these errors with kernel-2.4.18-24.8.0
during cd-recording (or shortly after that)
CDRW model: "LG CD-RW CED-8080B"
I have 
kernel /vmlinuz-2.4.18-24.8.0 ro root=LABEL=/ hdc=ide-scsi
in grub.conf.
The burned CD seems OK.

Comment 2 Alan Cox 2003-06-05 14:54:31 UTC

Something else tried to access the bus but timed out (the fixate locks the bus
for a long time).
The kernel messages while scary are ok in this situation.
