How does it work w/o libata-tj?

Your drive/controller causes HSM violation probably while executing a
SMART command (maybe during PIO-in during READ DATA?, maybe we need to
dump feature, too). Can you try 'smartctl -d ata -a /dev/sdx' and
report the result and how the kernel acts during that command?
Also, you've triggered a bug. It should try SRST after HSM violation
not revalidation. I had that code. I must have dropped it somewhere.
Thanks for finding the bug. :)

smartd is probably waiting for libata EH.

Can you post full boot dmesg?
