SATA link reset errors

Hi.

Of late, I am noticing link reset errors like the following in my kernel logs:

-------------------------
Jun 13 14:22:54 cellar kernel: [  325.280104] ata4.01: exception Emask
0x0 SAct 0x0 SErr 0x0 action 0x6

-----------------------------

These happen whenever there is even a moderate amount of disk i/o
going on. At first, I thought my 3+ years old Seagate 7200.10 SATA
disks were dying. So I went out & bought a new 1TB Seagate 7200.12
disk but these errors persist.

Re: SATA link reset errors

Hi Anton.

Thanks for the pointers! I'll check tonight what kernel version I'm running & switch to mainline builds if necessary.

However, I'm not using Samsung BIOS or HDD so not sure if it's the same issue...

Re: SATA link reset errors

I just wanted to show the logical path how to fix such issues ;-)
So if the latest mainline kernel couldn't solve the issue you would
need to file a bug report at
https://bugzilla.kernel.org directly and push a patch back to ubuntu later.

Good luck with it.

Cheers,
Anton

I tried the 2.6.35rc1 mainline build provided by Ubuntu & the errors persist.

So filed a bug report :)
