Bug#522234: debian-installer: Fails to boot on amd64 >4GB RAM
Package: debian-installer
Version: 20090123
Severity: normal
Hi,
I am booting an amd64 host with PXE method, once i get to the first
screen i press 'Install'......
Decompressing Linux... Parsing ELF... done.
Booting the kernel.
Aperture beyond 4G. Ignoring
Your BIOS doesn't leave a aperture memory hole
Please enable the IOMMU option in the BIOS setup
This costs you 64MB of RAM
PCI: Cannot allocate resource region 1 of device 0000:00:14.0
<halt>
I had etch installed succesfully and BIOS was ok. When updating
linux-image from 2.6.18 to 2.6.26, .26 never booted on my system. I
guess the failure was related to this issue. I have tried newer kernel
versions, .28 and .29, compiled at home and linux-image from unstable
and it works fine.
Tracking this issue I got to the idea that having >4GB (my system has
8GB) does not leave space to allocate AGP devices.
If you need more info, testing or whatever, feel free to ask me for it.
Kind regards
