ACPI and CDROM problems

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I have an inspiron 6400, using kernel 2.6.17 together with harddisk
suspend.  This laptop shows severe problems at resuming if a music CD
is in the drive.  In many cases it works fine, but sometimes[*] it
happens that the process stops after these lines have appeared on the
screen (approximately):

  sr0: scsi3-mmc drive: 24x/24x writer cd/rw xa/form2 cdda tray
       Uniform CD-ROM driver Revision: 3.20
       sr 1:0:0:0: Attached scsi CD-ROM sr0

It takes about 20 seconds, then a normal reboot happens.

Either the cdrom drive has a problem with recovering, or the resume
process doesn't wait long enough before continuing.

Before sending various configuration and log data I wonder what I
shall specifically do to improve debugging so that you get meaningful
data in case it is a new problem (I searched the archive but doesn't
found something relevant).

Maybe it isn't a bug at all, and I just have to improve configuration
-- please advise.
