need CONFIG_PNPACPI=y in ia64 config
Last modified: 2007-11-30 17:11:37 EST
Attempted installation on serial console fails with:
No ttyS device at MMIO 0xff5e0000 for console
This was using network boot images downloaded from
download.fedora.redhat.com/.../development/ia64/os/images on 2006-07-06.
The problem is that CONFIG_PNPACPI=y needs to be specified in the kernel config.
This is a new requirement in 2.6.17, since the acpi components were all added
to PNP, so 8250_pnp takes over hooking up the serial ports. As a result,
CONFIG_PNPACPI=y is needed to make the serial console available.

This looks sane. Dave, when you get a chance please commit this -- headless
installs are broken :(
