2.6.26 to 2.6.29 are fine -- the commit responsible was introduced in 2.6.30,
so only those kernels >= 2.6.30 exhibit the problem. For searching
purposes (so that Debian unstable etc can backport the fix to their
2.6.30 kernel), the error causing the panic at boot was:
General Exception: IA-64 Reserved Register/Field fault (data access) 48
and occurred a few lines after "ACPI: PCI Root Bridge [PCI0] (0000:00)"
