Has anyone figured this out yet? Here's a traceback from my
Thinkpad R40 (I get the same message above). I was able to
get the kernel to boot once by disabling atapicam, but even
that doesn't work any longer. The trace just moves from
xpt_foo() to g_conf_foo(). The trace from below is with
atapicam built into the kernel.
This damn thing doesn't have a serial port on it from what
I can see, so the information below is hand-scribed.
5.2.1-release worked on this as long as ACPI was disabled.
