I saw somewhere that this is a kernel bug that manifests when SMP support is enabled on an AMD64 system. If memory serves, the problem is in the CPU enumeration code.
I was able to work around it by building a custom kernel, which was based on the current Ubuntu Intrepid kernel but with SMP support turned off (I also had to disable a couple of things in the Ubuntu extra drivers section using 'make menuconfig' in order to get the kernel to compile). With the new non-SMP kernel my machine is able to suspend and resume. However, the video is not getting initialized correctly, and the image jumps around the screen at high speed so the machine is basically unusable. I am looking for info on how to configure the ACPI support so I can play with VBE stats, POSTing, and such (it was /etc/defaults/acpi- support a couple of versions ago, but that file seems to do nothing in Intrepid). $ uname -a Linux imbrium 2.6.27.2-cdk #3 Fri Jan 2 17:13:31 EST 2009 x86_64 GNU/Linux $ lspci 00:00.0 Host bridge: ATI Technologies Inc RS480 Host Bridge (rev 10) 00:01.0 PCI bridge: ATI Technologies Inc RS480 PCI Bridge 00:04.0 PCI bridge: ATI Technologies Inc RS480 PCI Bridge 00:05.0 PCI bridge: ATI Technologies Inc RS480 PCI Bridge 00:12.0 IDE interface: ATI Technologies Inc IXP SB400 Serial ATA Controller (rev 80) 00:13.0 USB Controller: ATI Technologies Inc IXP SB400 USB Host Controller (rev 80) 00:13.1 USB Controller: ATI Technologies Inc IXP SB400 USB Host Controller (rev 80) 00:13.2 USB Controller: ATI Technologies Inc IXP SB400 USB2 Host Controller (rev 80) 00:14.0 SMBus: ATI Technologies Inc IXP SB400 SMBus Controller (rev 83) 00:14.1 IDE interface: ATI Technologies Inc IXP SB400 IDE Controller (rev 80) 00:14.2 Audio device: ATI Technologies Inc IXP SB4x0 High Definition Audio Controller (rev 01) 00:14.3 ISA bridge: ATI Technologies Inc IXP SB400 PCI-ISA Bridge (rev 80) 00:14.4 PCI bridge: ATI Technologies Inc IXP SB400 PCI-PCI Bridge (rev 80) 00:18.0 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] HyperTransport Technology Configuration 00:18.1 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] Address Map 00:18.2 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] DRAM Controller 00:18.3 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] Miscellaneous Control 01:05.0 VGA compatible controller: ATI Technologies Inc RS482 [Radeon Xpress 200M] 06:01.0 Ethernet controller: Realtek Semiconductor Co., Ltd.
