Dear Maintainer, When the laptop-mode was activated, I was getting in `dmesg` similiar messages every few seconds :
Feb 10 22:21:26 chernomorets kernel: [ 488.561908] sd 0:0:0:0: [sda] Synchronizing SCSI cache Feb 10 22:21:26 chernomorets kernel: [ 488.563039] sd 0:0:0:0: [sda] Stopping disk Feb 10 22:21:27 chernomorets kernel: [ 489.918355] sd 0:0:0:0: [sda] Starting disk After a non regular time, the disk did not start again, the system was frozen (cannot use applications on kde, cannot log in a virtual console). The last messages in syslog are: Feb 10 22:22:02 chernomorets kernel: [ 524.697773] sd 0:0:0:0: [sda] Synchronizing SCSI cache Feb 10 22:22:02 chernomorets kernel: [ 524.698990] sd 0:0:0:0: [sda] Stopping disk ^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@ I removed/purged the package. Finally, in order to reproduce the messages, I reinstall it, and everything seems to come back to the normal. It might be a configuration problem. Sorry for these messages.
