Created attachment 134001 [details] the dmesg information of ubuntu 14.04 TLS I got the error from my ASUS K450JF (OS : ubuntu 14.04 ; disk : HGST HTS541010A9E680 1T gpt ; cpu : i7-4700HQ ) . It causes the OS to jam. And ASUS maintenance engineer said " your disk is ok and no bad sectors". So it may be a bug and what is wrong with my laptop. More information in the attachment. error information(from dmesg): [ 190.709673] ata6: exception Emask 0x50 SAct 0x0 SErr 0x4090800 action 0xe frozen [ 190.711097] ata6: irq_stat 0x00400040, connection status changed [ 190.712264] ata6: SError: { HostInt PHYRdyChg 10B8B DevExch } [ 190.713302] ata6: hard resetting link [ 190.713320] ata3: exception Emask 0x50 SAct 0x0 SErr 0x4090800 action 0xe frozen [ 190.713900] ata3: irq_stat 0x00400040, connection status changed [ 190.714523] ata3: SError: { HostInt PHYRdyChg 10B8B DevExch } [ 190.715181] ata3: hard resetting link [ 191.437594] ata6: SATA link up 6.0 Gbps (SStatus 133 SControl 300) [ 191.438545] ata3: SATA link up 1.5 Gbps (SStatus 113 SControl 300) [ 191.439004] ata6.00: ACPI cmd ef/10:06:00:00:00:00 (SET FEATURES) succeeded [ 191.439008] ata6.00: ACPI cmd f5/00:00:00:00:00:00 (SECURITY FREEZE LOCK) filtered out [ 191.439010] ata6.00: ACPI cmd b1/c1:00:00:00:00:00 (DEVICE CONFIGURATION OVERLAY) filtered out [ 191.441546] ata6.00: ACPI cmd ef/10:06:00:00:00:00 (SET FEATURES) succeeded [ 191.441549] ata6.00: ACPI cmd f5/00:00:00:00:00:00 (SECURITY FREEZE LOCK) filtered out [ 191.441550] ata6.00: ACPI cmd b1/c1:00:00:00:00:00 (DEVICE CONFIGURATION OVERLAY) filtered out [ 191.442668] ata6.00: configured for UDMA/133 [ 191.442672] ata6: EH complete [ 191.445565] ata3.00: configured for UDMA/133 [ 191.448998] ata3: EH complete
I got the same error when using ide (BIOS Compatible Mode). And I also got the same error when using Fedora 20(amd64).
[ 190.712264] ata6: SError: { HostInt PHYRdyChg 10B8B DevExch } Your disk changed. Thats usually either a cable problem or a power problem (the drive not getting enough power so dropping off the bus). The drive then comes back fine which makes me suspect a power issue. Either way the Linux kernel is simply doing the right things. It sees the hardware report a disconnect/reconnect and it probes the new device. If your box has all its file systems on the "old" device then it'll die.
Is there a way to improve it? I use the asus official notebook power now.
You would need to find out why the disk is disconnecting, or the cable losing link. You may want to ask for help on the Ubuntu forums about disabling - laptop mode - link power saving (ALPM) and see if either of those help stop the drive misbehaving. Bugzilla is not a support forum however, so you really need to work with your distro.

Is the same problem? Why the issue changed from "hard resetting link" to "soft resetting link"? And How to reproduce this issue?Because it appears random.
Looks like you turned off ahci mode, so the controller is now operating in the legacy ata_piix mode which can't perform hard resets. The same underlying problem. The connection between the disk controller and disk is not reliable and drops off from time to time. The driver is doing what it can to recover from the issues reported by the hardware. It could be something as simple as the drive not being seated well enough and opening it up and reseating it could resolve the issue or it can be something far more complex electronically. Booting with "libata.force=1.5Gbps" might work around the issue too.
Today I tried it(Booting with "libata.force=1.5Gbps" and turn on ahci mode),but got the sample error.

Same as your original report - your disk decided to go away and come back. Nothing there that looks like a Linux bug. See Comment #4. Nothing here has changed, you need to work through your distribution.
Sorry, my description(Comment 8)was not detailed.Yesterday i met it on CentOS 7.0.1406. Now I got the error on centos 7(kernel 3.10)/Ubuntu14.04(kernel 3.13)/Fedora 20.If kernel is OK,my laptop may have some problems. Thank you very much.
Now I got more information from asus.They said "It is caused by intel节能模式(intel power saving model) and had no idea to solve the problem". How to turn intel power saving model off? Or,are there any other ways to help solving this problems?
I have the same Issue, it cropped up since a week or two ago. After one of the kernel updates (Ubuntu 14.10)...
