Mageia 3 Beta 3: Parallel reads from BluRay and DVD failed.

[elmago]

I have about 40 DVDs to back up to Blu-Ray media. So, I create copies of them, about 6 or 7 at a time in the hard disk; and then try to burn a 25 GB media fitting as much I could from these DVD copies in hard disk. None of these DVDs have compressed/iso image. All have standard file structures (please excuse my ISO 9660 vocabulary).

When I copied from both the LG Blu-ray and the LITEON DVD at the same time, the DVD read suddenly failed at halfway ... failing to read an image file of 2 MB with error #5. A pop up box showed that message. The system kind of hanged there and became unresponsive as I tried to see that image file using other Dolphin windows. The system became very very slow with mouse movement not being echoed on screen. After about a couple of minutes it recovered on its own. System Monitor was on and it showed cpu usage of 45% average during DVD reads.

The Blu-Ray is obviously a SATA on ICH10 of Gigabyte EP45-UD3R motherboard. The LITEON DVD is on the on-board IDE bus of the motherboard. The CPU is a i9550 core-2 quad OCed at 4GHz dating back from 2008 December. Video card is Radeon 3450 driven by Xorg's radeon driver and not fglrx.

Thanks.
