--- Comment #3 from Theodore Tso <tytso@....edu> ---
It's possible there is some kind of compatibility issue with the SATA driver on
your Sony Viao, but the point is with errors like these:

[13546.661310] ata4.00: failed command: WRITE FPDMA QUEUED
[13546.661315] ata4.00: cmd 61/08:00:2f:1d:0a/00:00:00:00:00/40 tag 0 ncq 4096

... and like these:

... there's little that we can do at the ext4 level.  Basically, the disk
device (or the Sony Viao's SATA chipset) is refusing to talk to Linux.

The Sony Viao has, historically, been notorious for using Windows-specific
hardware that doesn't work well with Linux.  I don't know anything about your
specific model, but there have been enough problems in the past that I avoid
Sony laptops like the plague if I intend to use Linux on them.  It's not by
accident that most Linux kernel developers tend to use Lenovo Thinkpads...
