I gave up with 5.3 on my SiI3512A with Seagate SATA disks because of
this (mine was not only TIMEOUT, but also FAILURE) and related panics.

OpenBSD current seems more stable on this hardware.  Pity really, as
I've been using FreeBSD for years, and they're not quite so friendly
over on the other side.

My VIA SATA stuff still seems fine with 5.3, so I have to pick between
a friendly OS (5.3), and one which can run VMware 4 (L*x).
