As you are asking for IDE/SATA controllers. I have a SATA controller: ATI Technologies Inc SB600 Non-Raid-5 SATA . I first experienced the problem when I enabled AHCI mode in BIOS.
I am running Intrepid AMD64 dmesg | grep ahci [ 2.480262] ahci 0000:00:12.0: version 3.0 [ 2.480288] ahci 0000:00:12.0: PCI INT A -> GSI 22 (level, low) -> IRQ 22 [ 2.480315] ahci 0000:00:12.0: controller can't do 64bit DMA, forcing 32bit [ 2.480415] ahci 0000:00:12.0: AHCI 0001.0100 32 slots 4 ports 3 Gbps 0xf impl SATA mode [ 2.480418] ahci 0000:00:12.0: flags: ncq sntf ilck led clo pmp pio -- Heavy Disk I/O harms desktop responsiveness https://bugs.launchpad.net/bugs/131094 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
