Hello,
this morning my centos 5 server (2.6.18-53.1.4.el5) failed on the dvd
device and disabled dma. The dvd-writer (/dev/hdg) is connected to the
following controller as a secondary master.
02:07.0 RAID bus controller: Silicon Image, Inc. PCI0680 Ultra ATA-133
Host Controller (rev 02)
There is also an harddisc as primary master connected on this
controller. This harddisc is the only device in the system that I put
to sleep with 'hdparm -S180 /dev/hde'.
The error messages are:
Jan 24 04:54:21 weidenwinde kernel: hdg: cdrom_pc_intr: The drive

Could this error caused by the hdparm sleep command for /dev/hde?
