[QUESTION] Promise PDC20269 problems with FreeBSD 5.3

[Daniel S. Haischt]

Hello,

recently I updated one of my FreeBSD boxes to
v 5.3. This box got a builtin Promise PDC20269
UDMA133 controller. Actually it's a controller
with two IDE channels.

So far if using the GENERIC kernel that comes
with FreeBSD, I do not experience any problems.

If using my own customized kernel I am getting
the following error message while booting the
system:

----8<--------8<--------8<-------8<-----8<-----
Interrupt storm detected on "irq10: atapci1";
throtteling interrupt source:
---->8-------->8-------->8------->8----->8-----

After some trail-and-error based investigations,
I did figure out that if I don't plugin any device
into IDE channel two, the just described error
does not occur.

So it has something to do with IDE channel two.

As an additional note - The controller works
under Linux, FreeBSD 5.3 (GENERIC) and FreeBSD
5.2.1 (custom kernel).

Any hints on how to solve this issue would be
greatly appreciated.
