ide-cd: cmd 0x25 timed out

I have three DL585 G2s servers all running the same system ROM, RHEL 4.5 kernel 2.6.9-55.

On two of the server I continually receive the following errors in the kernel log:

ide-cd: cmd 0x25 timed out
hda: lost interrupt
cdrom_pc_intr: The drive appears confused (ireason = 0x01)

A smartctl -a /dev/hda on the server that does not have the issue results in the following:

=== START OF INFORMATION SECTION ===
Device Model: TSSTcorpCDW/DVD TS-L462D
Serial Number: [No Information Found]
Firmware Version: HG01
Device is: Not in smartctl database [for details use: -P showall]
ATA Version is: 7
ATA Standard is: Exact ATA specification draft version not indicated
Local Time is: Mon Jan 18 15:24:11 2010 CST
SMART support is: Unavailable - Packet Interface Devices [this device: CD/DVD] don't support ATA SMART
A mandatory SMART command failed: exiting. To continue, add one or more '-T
permissive' options.

The same command on the servers with the issue hangs and the process can't be killed.

Any information on this issue would be appreciated.

Thanks,
Chris H.

Re: ide-cd: cmd 0x25 timed out

Hello,

Based on ATAPI specs, 0x25 is "READ CAPACITY".

Try to use a CD (not a DVD media). If it works, then the hardware is faulty or the lens are not clean. Combos uses 2 laser wavelengths, 2 LED's.

If it is not working with a CD (use some original CD not a re-writed one), the drive is damaged.

Best regards,
