Description Mathias.Picker 2014-08-25 16:23:41 UTC
Switching to 10-stable my cdrom no longer works. The Laptop is an Acer 5553g.

I tried with a 9.2 live enviroment, it's still working fine, ruling out a hardware problem.

in 10-stable I get this error continously:

ahcich1: Timeout on slot 0 port 0
ahcich1: is 00000002 cs 00000000 ss 00000000 rs 00000001 tfd 50 serr 00000000 cmd 00006017

(aprobe0:ahcich1:0:0:0): CAM status: Command timeout
(aprobe0:ahcich1:0:0:0): Error 5, Retries exhausted

in 9.2 I get this:

cd0 at ahcich1 bus 0 scbus1 target 0 lun 0
cd0: <HL-DT-ST DVDRAM GT31N 1.00> Removable CD-ROM SCSI-0 device

cd0: Attempt to query device size failed: NOT READY, Medium not present - tray closed

and camcontrol shows the drive as:

I don't really need the cd, but this slows boot quite a lot and fills my log file with useless info, so I workaround would be great!
