Acer TM 603TER freezes on 5.x

[freebsd_daemon]

Dear list,

Installing FreeBSD 5.x (5.0, 5.1, 5.2, 5.2.1, and 5.3) on my Acer Travelmate
603TER the machine freezes after being up for a few seconds (just enough
time to mount my USB stick and save a dmesg). On 5.3R I get an "ata1-slave:
FAILURE - ATAPI_IDENTIFY timed out" error message (I am not sure if the
freeze is related to this), otherwise the install works okay (no freeze);
did not used to be so on the other 5.x-Releases (froze during install).

It does not matter if I boot with ACPI enabled or disabled; it always
freezes.

I do not experience that problem with 4.x (since 4.6R) and not with OpenBSD
3.5 and 3.6.

I would really apreciate some advice and help.

The dmesg from the last try (5.3R) is attached.

TIA

zheyu
