I am seeing a regression on the HP ia64 zx1 platforms when using a .config with CONFIG_IA64_HP_ZX1=y. Oddly it works OK with CONFIG_IA64_GENERIC=y. During bootup it panics with: Kernel panic - not syncing: Unable to find SBA IOMMU: Try a generic or DIG kernel I can provide the full console output if that is helpful. Also, please let me know if there is any other data I can provide that would be helpful. Using git bisect I have narrowed it down to these 2 commits. These commits cannot be built separately as they appear to have code that depends on each other. commit 29b71a1ca74491fab9fed09e9d835d840d042690 Author: Thomas Renninger <trenn@xxxxxxx> Date: Mon Jul 23 14:43:51 2007 +0200 ACPI: autoload modules - Create ACPI alias interface Modify modpost (file2alias.c) to add acpi*:XYZ0001: alias in modules.alias like: grep acpi /lib/modules/2.6.22-rc4-default/modules.alias alias acpi*:SNY5001:* sony_laptop alias acpi*:SNY6001:* sony_laptop for e.g. the sony_laptop module. This module matches against all ACPI devices with a HID or CID of SNY5001 or SNY6001 Export an uevent and modalias sysfs file containing the string: [MODALIAS=]acpi:PNP0C0C: additional CIDs are concatenated at the end.
