ahcisata0: BSY never cleared, TD 0x80

[tlaronde%polynum.com@localhost]

Hello,

On a Seagate 1.8T internal drive (with GPT partitioning), and under
NetBSD 5.1.2 amd64, on heavy i/o the disk freezes and the system goes
unresponsive, obviously stucked waiting for the disk.

There are:

ahcisata0: BSY never cleared, TD 0x80

messages too. (Furthermore, there are, when trying to get smart
informations via atactl(8):

wd1: dos partition I/O error

is this the partitioning? A dedicated "hidden" partition precisely for
SMART logs?)

The disk may be the problem (I mean, it could be a hardware problem with
the disk, even if SMART reports everything as reliable, with a high
number of read error rate that seems to be "normal" for Seagate drives
according to what is found on the Web...).

There is kern/47097.

What is the status of this?

TIA
