[Bug 1247806] Re: Kernel resetting SATA link
I figured that for me the error messages disappear if you set the SATA
mode to 'Compatibility Mode' instead of 'AHCI' in the BIOS. Ubuntu still
booted after this change. I could not find a relation to the Optimus
Graphics switch as reported at
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/888764.

Title:
Kernel resetting SATA link
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
On Ubuntu 13.10 I encounter kernel reseting SATA link in connection
with temporary system freezes (KDE lags). Such a bug has previously
been reported here
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/888764 for the
same hardware but older software. This behavior has also been reported
here https://lkml.org/lkml/2011/10/26/11 for same hardware and in
connection with unresponsive KDE. For me it occurs if the system is
under high load.
In such situations dmesg says repeatedly:
