I'm getting a kernel oops on the intel woodruf P4 motherboard under 
2.4.22pre10.  This config worked fine under 2.4.21.  The output of 
ksymoops is attached, and the raw oops is attached.

ksymoops 2.4.4 on i686 2.4.20-8smp.  Options used
     -V (default)
     -K (specified)
     -L (specified)
     -O (specified)
     -m /boot/System.map-2.4.22-pre10 (specified)

  It seems to only effect the newer mobos, and/or bios.  As my older system is
quite happy with acpi.  The older system appears to have 205 rev, while the
newer has a 303 rev.

Would you please try last ACPI (2.6.0-test4)
Would you please post acpidmp?
Thanks a lot.

  I'll see what I can do the system was moved into production.

Samuel, no need to chase down the system, I've reproduced this in my lab. 
 
I used a -204 S845WD1-E motherboard running BIOS 8 (latest) 
with 2.4.22 on top of RHL 9.0

acpidmp output

> SSDT @ 0x07fe2fdd
The 0x24 byte header copy from this address overflows onto the 1st byte of the
next page,
where we get stung by an off-by-one bug in ioremap() that has mapped only 1
page for
us here when we need two.

This explains why a different revision of the BIOS can work -- because all it
has to do
is change the start address of this table by at least 1 byte and it will not
hit this bug.
