Comment 48 for bug 75295

Thanks for the time regarding the compile-time kernel option. I will keep that in mind in case the problems like this become more pervasive.

Ok, it look like we can narrow this down to ASUS drives. If anyone is familiar with their firmware that might help us further.
Meanwhile, I'm experiencing the same problem again, this time only on my ASUS drive, not the SONY drive, and the problem only occurs intermittently. I'm now also convinced that it's not related to libdvdcss, even though the problem disappeared the fist time right after installed that package.
I honestly don't know where to begin to look for the source of the problem, so any ideas would be great!

I've also had other issues where the IRQ timing starts to get out of what and the entire system starts to go insane, with the hard drive spinning out of control; this happens randomly, although lately it hasn't happened as much, since I disabled most ACPI options in the BIOS. My error logs indicate that this problem is due to the IRQ timing being off which is often caused by CPU time scaling. I'm thinking that the problem here with the DVD drives might be related since the symptoms are very similar. If you have this problem, perhaps try disabling certain ACPI / CPU time scaling / other power management settings (espcially on the laptop!) which might be causing this problem.

Thanks, I hope we find a solution soon. Anyone from the hald team or the kernel team responding?
