5.4-STABLE changes breaks IDE boot (was Re: 5.3 -> 5.4 breaks ATA (Intel ICH2))

[Michael L. Squires]

This may be a similar problem to the one discussed in the Intel ICH2 
thread.

System is a Toshiba 8100.  System boots from a 5.4-STABLE kernel compiled 
5/3/2005 but locks up on boot with kernels compiled in the past few days.

I re-cvsup'd after the first lockup and build a GENERIC kernel, same 
results.  The atapci0 lines were divided by the mailer to fit into an 80 
col line, I've added the "\".

The only difference I can see is that the working kernel allocates port 
0xfff0-0xffff to atapci0, and both the non-working kernels don't allocate 
those ports.  This is the only difference I can see between the working 
and non-working output from the boot process.

The complete old dmesg is attached.
