G'day,

ACPI enabled kernels configured for a Dell Inspiron 8600 exhibit the following 
problem:

The system boots up and, with the exception of a non-functional cd0 device, 
works as expected. Attempts to mount this device fail with the following 
error message

Jul  6 21:14:51 husky /netbsd: piixide0:1:0: lost interrupt
Jul  6 21:14:51 husky /netbsd:  type: atapi tc_bcount: 0 tc_skip: 0

Options ACPI_PCI_FIXUP was enabled in the above kernel. When commenting out 
this option, the cd0 device is detected and functional, however, the wi0 
(AVAYA wireless PCMCIA - 802.11b) is not functional presumably due to the 
PCI-CardBus Bridge not being detected, e.g. no cbb0 device.

Has anyone else seen this problem? Is it a known bug? Searching with Google 
didn't reveal anything that would help me in solving this problem.

Due to size, I've not included the dmesg output and kernel configuration file 
here, but they are available as NetBSD-2.0G_dmesg.txt and HUSKY-acpi in my 
home directory on ftp.NetBSD.org

Any suggestions?
