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. Werner [*] At least 1 out of 10 tries.
