When inserting a DVD into the drive (HL-DT-ST GSA-T50N) it sometimes
gets stuck and keeps spinning forever without recognizing the disc. Then
a reboot is necessary to remove the disc.
I am using a vanilla 2.6.28 x86_64 kernel.
lspci | grep SATA:
00:1f.2 SATA controller: Intel Corporation ICH9M/M-E SATA AHCI
Controller (rev 03)
The controller is set to AHCI mode ("Enhanced") in BIOS.
The drive works in Windows (also AHCI) so I would rule out a hardware
problem.
Here is the (maybe relevant) dmesg output from bootup to timeout:
