[Please CC me, I'm not subscribed to LKML.] I recently picked up a new server of really new hardware, and I've run into a number of issues with the latest git HEAD kernels. I'll make separate posts for each of the issues. CPU: Intel Core 2 Duo E6400 Motherboard: Intel DG965RY BIOS revisions: July/07/2006 AND September/06/2006 (tried both) The most significant of them - is that somewhere between 2.6.17.11 and 2.6.18-rc6-git4, MMCONFIG is now being used, but leads to a complete hardware hang (SYSRQ does not respond). As of the current HEAD, I need to boot with pci=nommconf OR acpi=off, otherwise the machine completely freezes a short while into the PCI detection routine. Using acpi=off disables SMP, which is not desirable on this box, but otherwise does work. All of the following boot params lead to a failure: pci=assign-busses acpi=strict pci=noacpi acpi=ht pci=nomsi At the following URL, I have photos and transcriptions of the kernel boots, as well as dmesg output from working 2.6.17.11 and .18-rc7-git1 with pci=nommconf. http://www.orbis-terrarum.net/~robbat2/x86_64-mmconfig-failure/ -- Robin Hugh Johnson E-Mail : [email protected] GnuPG FP : 11AC BA4F 4778 E3F6 E4ED F38E B27B 944E 3488 4E85
